Once again, the 2015 MBP locked up ....
Posted by: Diana
Date: April 16, 2021 07:52PM
.. and I got tired of waiting and closed the lid to bring it home ...and it rebooted IN THE BAG, and so I lost the work I had done.

A little information is in order: I had started with one reference manager software; they dropped the Mac. I went to another one in grad school (expensive but I didn't have to pay for it) but it didn't do what I needed, and subsequently went to one that did. I paid for this one out of my own pocket, but I was happy with it. They went out of business. So I went to another one that apparently will do what I need it to do. They are responsive to issues you may have (I have had a response within a few hours, late at night and even on the weekend) and so I don't want to change if I don't have to.

The software will check for duplicates and allow you to keep one/delete the other(s) as well as consolidate information into the reference you want. Originally, I was under the impression that the upper limit of references was <unlimited> (really?) but now I'm told that I need to split up the reference list as I've gone well beyond what anyone thought was probable. Whatever. First, however, I want to make sure that I don't have multiple copies of a reference as it will only cause headaches down the road. Imagine: you have read the paper, make annotations, and know you have done so, but you cannot find it, or, conversely, you think that you have not made annotations, but find that the pdf of the reference is marked up, but the reference in the software has no mention of anything. Now I will have some X number of lists, with potentially X number of copies of the SAME paper, depending if it hits the topic(s) for the list(s). Yay.

Well, everything seems to go well, until it doesn't. The computer itself slows down, as in a crawl bad enough to swear that I'm using a Windows machine and a BSOD is imminent. A look at the Activity Monitor shows that the software is using a LOT of memory (this machine is maxed at 16GB) with high memory pressure (21 GB), and the only remedy is to reboot. However, I'm in the middle of the duplication-elimination-process, and there is NO save and restart without just dumping the work that has been done and restarting it all over again. This isn't a 15-minute job, but something that takes days to weeks to get it done, with each change taking some 20-30 seconds to save and then allow you to go on to the next item.

So, yes, I know that the software has issues. However, I'm wondering if this MBP is also having hardware issues. I bought it second hand from our sponsors; the screen has a "glitch" that occasionally shows itself momentarily but cannot be reproduced. There is a pattern of white pixels that only show up when a evenly dark background is shown that lends credence to the idea that it has been either stepped on or leaned on or crushed to some degree. Otherwise, it seems to work okay (notwithstanding the issues that I've previously written about) even with the sometimes-pauses that I see.

Anyone have any ideas here?

I am hoping beyond hope that the 15" MBP M1 will be announced on Tuesday, but it may be hamburger for me today. I've been sorely tempted to go for the 13" M1 MBP but since the announcement of the Apple Event I'm finding myself hesitant.

Re: Once again, the 2015 MBP locked up ....

1. What's the name of the software.

2. Your process explanation wasn't clear to me-it was too abstract, with no examples. What does it mean that multiple copies of a reference will cause headaches? Maybe it's my lack of familiarity with the software/content area....

3. If it were me, I'd export the reference list (if possible), put it into Word or Excel, and Sort it alphabetically. that should make duplicates pop out, because they're be next to each other. In Excel, you could even write a formula that would identify duplicates for you.

From the information you provided, that's what I can offer. Maybe others can glean more from the crash report; I'm a novice with them.

Good luck!

P.S. What are you writing? How long is it? How many reference do you have?

The crash log points to a graphics card issue, but it could be that it overheated in your bag and crashed. It isn’t a great idea to put a frozen laptop in your bag, if it can’t go to sleep because it is frozen it is going to roast.


As far as your software issue....I’m guessing without knowing how the software works but it seems like a resource utilization issue. Either you need more ram and faster drives or the code/database isn’t optimized for as much data as you have in it or a combination of the two. Complex compare queries can eat up resources if they are not optimized to how the data is stored. Especially if there is no indexing happening.

From what you describe, a Mac Pro might be a better choice than a MacBook.

1. The software is Bookends. It is a reference manager. It allows me to put a PDF of a scientific paper into the computer, and be able to search the "database" and group the hits according to the search words. I started with Reference Manager for Mac, which dropped the Mac and went Windows only; then went to EndNote with a manual system of folders and physical paper articles; then to Sente which allowed me to make it all electronic and thus eliminate the clutter and sea of paper, and these guys went out of business; to Bookends.

2. In the journey from one software package to another, I have found that some of the attachments (the PDFs) are not associated correctly, as some random PDF not associated with the particular reference may be attached (or not). For instance, there exists:

"Variable step-size based method for acoustic feedback modeling and neutralization in active noise control systems" in the Journal of Applied Acoustics, 2011, pages 297-304. It has an attachment. When I look at the attachment, it could be the correct paper, or some random thing from say, the journal Analyst or the journal Chromatography or whatever. There may be two (or more) references saying the same thing but missing some information that the other one contains. There could be thousands of such duplicated references in the database, or thousands of misattached things. The publishers want from (free) to $120 or more per paper, and there are some 180,000+ references. Not all of them are something I want or need at this point. Thus, I am in the process of eliminating the duplicates, the unwanted stuff, the orphaned ghost attachments, and the misattached crap.

3. Bookends already will show the duplicates. To do as you are suggesting, I would have to:

a. Export the database in a form that either Word or Excel would use, ignoring the attachments

b. Go through each and every one of them, stripping out the duplicates and combining the information into one reference per paper; Word would allow it; however, the larger the document the more difficulty you can have with a Word document (as I found in grad school). Excel also has limits, unless I want to give more money to Microsoft to update to the latest and greatest. I should admit now that I HATE the subscription model.

c. Reimport the resultant set to a new Bookends library. It is picky as to how you can import, and I'm still working my way through it. It isn't necessarily intuitive.

d. Find the correct attachments and re-attach them, including the supplemental information as well as any video, text, or other documentation that was submitted and thus available to help explain or show what the paper was about. Not all of the supplemental information is available forever, so you have to get it while you can.

OR

I could just use Bookends to search for duplicates, have it allow me to check them, make the appropriate changes and then when I get to the end of the list allow it to delete the duplicates I tell it to delete. I then can search for duplicates using a slightly different criteria, and go through the process again. Then I will need to go though everything and make sure the attachments are correct.

As to what I am looking at:

The deconvolution of overlapping peaks using high-performance liquid chromatography (HPLC) with electrochemical detection (ECD), using multiple detectors in sequence. HPLC-ECD is sensitive but not necessarily selective as to what analytes it detects, and thus the use of multiple detectors in sequence set for different potentials will give a more complete picture of the compound in question. Set the potential high enough and any electroactive compound will give a signal; set the potential too high and you can electrocatalytically break water into hydrogen and oxygen.

I am trying to determine how to determine multiple components (analytes) found in a mixture of several compounds in solution, and there is a real possibility that two compounds will come out at the same time in the chromatogram. An example of this would be determining which neurochemical compounds are present and at what levels in spinal fluid. One could analyze it several times, setting the detectors at different potentials and seeing the resultant signal levels or using different column/mobile phase combinations and thus get different ordering of the compounds eluting from the end of the column. The problem here is that the sample may not stay consistent over time as the analytes will degrade with time and temperature. Or one could do an analysis using a sensitive and low-noise method such as mass spectrometry, and then use statistical methods to determine the composition of the mixture.This has already been done, and done well. However, the statistical methods tend to fall apart when the data contains additional noise (greater than say 3%) and other sources of variability (like adding instrumental effects associated with either the detector or the separation method). I am looking specifically at using HPLC-ECD which is notoriously noisy in relation to other analytical methods, and most statistical analysis methods (if not all of them) fall apart when the amounts of the analyte approach the detection limits of the instrument or when it approaches the noise level present in the system. Two similar compounds will act similarly on the column, and will act similarly using electrochemical detection; if you have multiple electrochemical cells you could set them at different potentials and thus exploit the electrochemical differences between the two compounds as you can often induce different amounts of signal based on the potential the electrode is set for. Since you can exploit time in the analysis, as well as the current observed as a function of time for EACH of the detectors, statistical methods that make use of multiple dimensions (time vs signal level vs potential the electrode was set for) would be the way to go. There are many methods, with some more appropriate than others. Some are more susceptible to noise than others, and it is helpful to know which ones have this issue. Thus, the large number of references. I won't know what will work without examining them, and often it takes a deeper dive to understand the method du jour and more specifically where it falls apart.

I am still in the search, read the material, understand the material, and test any ideas against data I currently have stage. Everything I have seen and read says basically that it can't be done, but only because no one is reporting on it. Unfortunately, no journal reports the failed experiments and most will only publish things that work (and are exciting!) so the things I try may have already been tried and found insufficient.

The crash log points to a graphics card issue, but it could be that it overheated in your bag and crashed. It isn’t a great idea to put a frozen laptop in your bag, if it can’t go to sleep because it is frozen it is going to roast.


As far as your software issue....I’m guessing without knowing how the software works but it seems like a resource utilization issue. Either you need more ram and faster drives or the code/database isn’t optimized for as much data as you have in it or a combination of the two. Complex compare queries can eat up resources if they are not optimized to how the data is stored. Especially if there is no indexing happening.

From what you describe, a Mac Pro might be a better choice than a MacBook.

C(-)ris,

Thanks.

It froze for about 30 minutes prior to me giving up and putting it in the bag. I feel it crashed before I put it away, it just didn't give me an indication of it. I know it isn't a good idea to put the laptop in the bag in such a state, but I just needed to get it to the car and then take it back out again to prevent overheating. Normally I would just carry it out to the car in my arms, but it was raining today. This isn't the first time it happened, just the first time I caught it. I have let it run overnight, only to look at it in the morning and realize that it had rebooted sometime that night.

The software is a separate issue, and I'm working on reducing the size of the database.

I would love a Mac Pro, but I can't justify the cost of one. I've been keeping an eye on the reports of the M1 systems as they are looking promising. As this whole thing is not my main line of work, portability is a good thing as it allows me to work on it at odd times during the day, such was downtime at work.

... and there is NO save and restart without just dumping the work that has been done and restarting it all over again. This isn't a 15-minute job, but something that takes days to weeks to get it done,...

Can you please clarify this part???

Man, if there is a program that works for you on windows, I would just buy a cheap windows laptop...It's not THAT bad. My wife has had similar problems (using MATLAB, etc.) with mass overheating, etc. with 3 different Macs. Like you, she just puts up with it. Maybe the M1 will take care of those problems, but who knows if the software will be available for it? Good luck though.

I start by having Bookends search for duplicates It compiles the list, asking me what I want done with what it finds: (a) delete them, uninspected and sight unseen; (b) mark them, allowing one to go through the entire library and manually find each duplicate, compare and combine information into the one reference I wish to keep (a long tedious process as the duplicate and its mate may not be necessarily next to one another and I estimate will take a few months; OR (c) have Bookends display the duplicates side-by-side, temporarily marking what it thinks I want deleted, and thereby allowing me to easily see the duplicates, make my changes and go to the next one. This last choice will take an estimated 2-3 weeks and it cannot be changed once the choice has been made to say (b) above. I can then tell it to delete the temporarily marked references. There is no pause, save, and come back to it later at this stage. If I have to restart the laptop, either I cancel the operation or I try to have it delete stuff that may not be what I either need nor want. This is what I mean by “there is NO save and restart without just dumping the work that has been done and restarting it all over again. This isn't a 15-minute job, but something that takes days to weeks to get it done” and the reference to time goes like this: say it finds some 1500 references it calls as duplicates, and each one has three changes that need to be made; each change takes some 45 seconds or more to see it and make the changes, and some additional 20 seconds to save each change, for a total of say 2 minutes per reference. 2 minutes times 1500 references = 3000 minutes or right at 50 hours to get through them. So it will take a week of doing nothing but this, irrespective of my actual paying job and other obligations, or several weeks using what time I can get.

It is choice (c) that I am working with as it supposedly will take less time/be easier. Either I go through the whole process of inspecting and changing and combining all the way to the end of however many references it calls duplicates and then having the unwanted references deleted, or just trust Bookends to “know” what is what I need (hint: it doesn’t). I have had marked references suddenly become unmarked, so that route isn’t the best.

Admittedly the software has issues in its execution but show me one that doesn’t.

Maybe the M1 will take care of those problems, but who knows if the software will be available for it? Good luck though.

I tried using Windows years ago but found it unstable for my purposes. I gave up on it after losing days of calculations a few times, and triggering crashes repeatedly. For MATLAB I just set it up on the Mac desktop and let it run, and it hasn’t been problematic. The M1 should help a lot, if everything (or even most) one hears about it are true and not just hype.

Perhaps things have changed on the Windows side. But after having experienced the frustration of repeated set backs of wasted time and money, both of which are in somewhat short supply, I’m hesitant to change over again.

Bookends is already available on the M1 and I understand that it runs natively. The developers are quick to respond if needed, and there is an active board to discuss things, suggest features, etc which is monitored and feedback is often available there. This is quite unlike the others I have tried as any issues you see and send to them often leave you with the feeling that you have thrown your concern into a black hole, never to be seen again.

The memory footprint growing as much as it does points to either a memory leak, or a poor algorithm being used that requires a lot more RAM than your MacBook Pro can provide. You could contact the developers to see if they have either a fix or settings that would reduce the RAM usage. But basically it looks like some resource is being exhausted, RAM, page file space, file links, or whatever.

My wife has been Mac only for a decade and a half.

Her job switched to Windows.

After figuring it out, the OS, she really likes it.

Someone, somewhere, did not clean up after themselves (driver code, or buffer management, or thread management) when a thread died and was reaped without releasing resources it had locked (or multiple threads).

This is not a user error.

I would love a Mac Pro, but I can't justify the cost of one. I've been keeping an eye on the reports of the M1 systems as they are looking promising. As this whole thing is not my main line of work, portability is a good thing as it allows me to work on it at odd times during the day, such was downtime at work.

A Mac Pro doesn't have to be a new, multi thousand dollar model. A $400 2010 or 2012 model should do the job as well as your MBP. Obviously, you lose portability with a Mac Pro. And of course, new M1 announcements might make it moot.

... and there is NO save and restart without just dumping the work that has been done and restarting it all over again. This isn't a 15-minute job, but something that takes days to weeks to get it done,...

Can you please clarify this part???

I start by having Bookends search for duplicates It compiles the list, asking me what I want done with what it finds: (a) delete them, uninspected and sight unseen; (b) mark them, allowing one to go through the entire library and manually find each duplicate, compare and combine information into the one reference I wish to keep (a long tedious process as the duplicate and its mate may not be necessarily next to one another and I estimate will take a few months; OR (c) have Bookends display the duplicates side-by-side, temporarily marking what it thinks I want deleted, and thereby allowing me to easily see the duplicates, make my changes and go to the next one. This last choice will take an estimated 2-3 weeks and it cannot be changed once the choice has been made to say (b) above. I can then tell it to delete the temporarily marked references. There is no pause, save, and come back to it later at this stage. If I have to restart the laptop, either I cancel the operation or I try to have it delete stuff that may not be what I either need nor want. This is what I mean by “there is NO save and restart without just dumping the work that has been done and restarting it all over again. This isn't a 15-minute job, but something that takes days to weeks to get it done” and the reference to time goes like this: say it finds some 1500 references it calls as duplicates, and each one has three changes that need to be made; each change takes some 45 seconds or more to see it and make the changes, and some additional 20 seconds to save each change, for a total of say 2 minutes per reference. 2 minutes times 1500 references = 3000 minutes or right at 50 hours to get through them. So it will take a week of doing nothing but this, irrespective of my actual paying job and other obligations, or several weeks using what time I can get.

It is choice (c) that I am working with as it supposedly will take less time/be easier. Either I go through the whole process of inspecting and changing and combining all the way to the end of however many references it calls duplicates and then having the unwanted references deleted, or just trust Bookends to “know” what is what I need (hint: it doesn’t). I have had marked references suddenly become unmarked, so that route isn’t the best.

Admittedly the software has issues in its execution but show me one that doesn’t.

There has to be a better solution. This is simply not acceptable.

1. The thread from The Caber and his/her comments might help the developer to tix this problem, if you send it to the developer.

2. Ok, if I understand correctly: You have a large library of documents. The software provides links to them, and allows you to search them for keywords. Is that correct?

It sounds like the library and/or index is corrupt. Here's one thing I'd consider:

Can you go into the library directly, and look at/export/delete specific documents? If so, I'd make two copyies of the library, and then delete the second half of Library A, and the first half of Library B, and then ask the software to reindex (which is what it sounds like you're doing, more or less). Maybe split the library into 4 parts, or 5, or whatever. Then reindex each part separately.

Then I'd try reintegrating the separate parts to recreate the master library, and reindex after I bring each part into the master.

Best case scenario, you have master library that works. Worst case scenario, you have four functional partial libraries which are correctly tagged, and you can then compare the indexes from them for duplicates, and eliminate the duplicates. That would require running 2, or 44 searches in the future

One more thing: if the software has ny kind of "restore corrupt index" function, I'd try that first.

Good luck! Let us know how it's going.
