Steps to reproduce:

Note: when the problem started I was using the beta branch, but now I forcefully downgraded to the release branch (which I assume is the 68), but the problem persists.

Up until say three weeks ago Thunderbird was working fine, but then it started hanging up, and the macOS task killer started coming up with "memory is gone", and it was always TB eating up gigabytes of memory. This happened a few times, while TB was still marginally usable, but now it has degraded into a state where TB either never comes up, eating all the memory, or it shortly comes up-- meaning the window gets started, and I get a few minutes of time to use it, but then the system grinds to a halt again.

Now I (as mentioned earlier, back at the latest release branch release, 68.6.0 I think), I tried starting it again, but the UI window has not come up yet, and according to top(1) it is chomping up my memory, now at 32GB and going up.

Actual results:

See above.

Wild hypothesizing: I do have a lot of local folders (that's the reason I am using TB...) so maybe it is doing some ambitious reindexing of the folders, and therefore eating memory like candy?

I should not have any especially gigantic emails like lots of big images or videos.

Expected results:

Thunderbird should not eat gigabytes of memory.

It would be nice to know what TB is trying to do. Is there a way get some logging information out of it?

This time it grew to 119 Gb before the macos Force Quit got tired of it. None of the other apps even breaches 1GB.

Please try starting Thunderbird in safe mode https://support.mozilla.org/en-US/kb/safe-mode-thunderbird

Flags: needinfo?(jhi)

Will try that.

But in the meanwhile, partial good news: as I was trying to bisect a little bit more when exactly this memory hogging started, I realized that the release Thunderbird 68.6.0 does NOT exhibit the bad behavior. So that is good news.

So I have now the 68.6.0 now running, with whatever extensions, haven't done anything explicit about them. Though I did start the currently running 68.6.0 manually with the spell

/Applications/Thunderbird.app/Contents/MacOS/thunderbird -P --allow-downgrade

It seems to be staying within sane limits, according to top about 570MB currently with my inbox.

I don't known if that disables something relevant (since I'd been running the beta channel up until last week, when the problem really got bad).

I will need to retrace my steps and install the beta alongside this one.

Flags: needinfo?(jhi)

aggressive indexing would/should not consume excessive memory.

two things to look at
tools > activity manager -- will provide some idea of what is running
help > troubleshooting > about:memory -- to show memory usage (although it isn't terribly reliable, and in high memory situations takes for ever to complete, IF it completes)

Severity: normal → critical
Keywords: perf

I found about the activity manager also from my "google research", but there is the problem that when this memory hogging starts, the UI side of Thunderbird becomes complete unresponsive.

Is there a way to enable some logging that would get out of the Thunderbird process? syslog? Especially if this is only a beta branch only problem, some developer debugging would not surprise me.

Ugh, now I am having trouble getting back to the beta releases because they insist on creating new profiles, which of course would not replicate my existing setup at all.

use startup switches
-P -allow-downgrade
And, if the issues is related to getting new mail the following might help
-offline

see https://developer.mozilla.org/en-US/docs/Mozilla/Command_Line_Options

Ok, managed to start 75.0b1 with my default profile (though it wanted to download some update and restart). Following what happens...

... and it went bad quickly (so my default profile, still using all the extensions). The UI went dead (the app window is not even coming up in the macos task manager!) so I cannot show you any activity monitor or about:memory. But I managed to start a shell watcher before it went bad:

The columns being:

ps axug|head -n 1
USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND

So it's growing fast again.

Next I'll kill this and try the same without the extensions.

(note: in the above the stray pid 25566 was me mistakenly trying to start another TB)

The 75.0b2 now running with the -safe-node, so all the extensions disabled, following the situation.

I looked at my add-ons and I don't have many, only four:

  • AdBlock Plus version 2.9.1 (quite old: June 7, 2017, no idea what it hasn't updated)
  • Dropbox for FileLink version ...

HEY! now it went crazy again (the UI went dead, and the memory use started climbing, and CPU spiked).

(I will finish my report on the extensions once I regain control.... but there were only four of them, and all disabled anyway)

This was the happy state:

Oh I see. I now killed the wild 75.0b2 and started 68.6.0 also in safe mode, and it seems that almost all my extensions are incompatible even with 68.6.0, so maybe they are all effectively disabled anyway? So I have:

AdBlock Plus
DropBox for FileLink
Provider for Google Calendar (the only one NOT incompatible for 68.6.0!)
Remove Duplicate Messages

But back to the memory monster: so it seems very reproducible with the beta builds that a few minutes after starting, the CPU spikes, and TB starts consuming large amounts of memory, becoming completely unresponsive, not stopping until the macos task killer steps in.

Here is a new log of the run, I customized the ps format a little, the monitoring script is now:

while true
do
ps -ax -o ucomm,pid,state,pcpu,pmem,vsz,rss,start,etime,command|grep Thunderbird|grep -v grep
sleep 5
done

I just started the beta in the safe mode

/Applications/Thunderbird-75.0b1.app/Contents/MacOS/thunderbird -P --allow-downgrade -safe-mode

and then did nothing on the UI:

The boring start:

(note on the above: even though the directory of the beta release is named "b1", the app managed to upgrade itself once, so it is now "b2")

New try, at 5 minute mark, boom:

I will attach the full log files shortly.

ps -ax -o ucomm,pid,state,pcpu,pmem,vsz,rss,start,etime,command output every 5 seconds from 2nd run of 75.0b2 (the directory name is wrong)

Thinking back when did I first start noticing this, it was probably last week's Wednesday, the 18th of March. I remember restarting my beta channel Thunderbird due to it nagging about having an update, maybe that was the b2?

Looking back out my release history, 74.0b2 shipped on 2/28, 75.0b1 on 3/13, 75.0b2 just yesterday 2/26

Component: Untriaged → General

So maybe it was the 75.b01 that I finally gave in and installed last week's Wednesday.

Do you want me to find and try the 74.0b2?

After some downloading and testing... it was definitely the 75.0b1 that brought the issue (and the 75.0b2 still has it). The 74.0b2 and couple of earlier ones I tested do not have it. At 5 minutes after starting Thunderbird, the CPU spikes and memory starts going fast. Attaching some logs soon.

Attached file tb-beta.log.gz —

-rw------- 1 jhi staff 22308 Mar 27 18:53 tb-71.0b1.log
-rw------- 1 jhi staff 40308 Mar 27 19:13 tb-73.0b2.log

-rw------- 1 jhi staff 28159 Mar 27 19:52 tb-75.0b2.log

Each of them has at least ten minutes worth of log.

Note that each time I did nothing at all with the TB.

(Very likely unrelated observation: the 75.0b2 had very noticeable CPU spike in the beginning when one needs to click a few times to get through the -P dialogs.)

FWIW I tried doing the "Troubleshooting information > about:memory > Save memory reports" every minute using the 75.b02 but as soon as the CPU spikes at the minute five, the TB becomes unresponsive ("spinny beach ball", in macos terms) and I was unable to save the report anymore.

(I also tried enabling the "Thunderbird remote debugging", but the guides talk of "Tools > Allow Remote Debugging", which does not seem to exist. There is "Tools > Developer Tools > Developer Toolbox" which opens up something, but that looks more geared towards web developer work, when all I wanted was being able to run "about:memory" from another process....)

I figured out how to get the memory snapshots via the Developer Toolbox, but that didn't help for getting the snapshot after the magical limit of 5 minutes: the debugging instance cannot get anything out of the hung instance.

Blocks: 1330872

I've been seeing 1-4gb memory usage on Mac.

I'm not sure we need to see your situation at the point where it is hung - ISTM the time leading up to that should be enough.

Can you attach a text file to the bug from help > troubleshooting > copy text to clipboard?

Flags: needinfo?(jhi)

Please clarify: at what moment you want that troubleshooting thing to be taken? The thing is that once things start going bad TB hangs completely, and I cannot precisely predict when that happens, so I would need to keep repeating doing the thing until TB becomes unresponsive. With the GUI one try always takes at least a few seconds. Therefore a command line invocation not bound to the GUI and my clumsy fingers would be so much better.

Flags: needinfo?(jhi)

IOW, is there a way to get the information of Help > Troubleshooting information withOUT going through the GUI?

Ok, I see, the Troubleshooting information is static. In that case, this about 3 minutes after starting and about 2 minutes before TB 75.0b2 became unresponsive:

Thanks for the info. Please attach troubleshooting as a file in the future.

So you only have one account, and it is pop? If you disable turn off the automatic download of messages via account settings startup and interval settings, does the high memory usage go away? Do you have message filters?

I'm unsure it will be revealing, but please record a log with instructions at https://wiki.mozilla.org/MailNews:Logging using
msgdb:5,timestamp,sync

Yes, I have only one pop account, to gmail.

I now started the 75.0b2 with the now customary --safe-mode, and disabled all the downloading from the account settings. It had both "load at startup" and "periodically" checked, but I disabled both.

Note, however, that the period for downloading seemed to be 10 minutes, not the 5 minutes, which seems to be the rather precise "things go pear-shaped" marker.

Even with the connections disabled, the CPU spike happened at the 5 minutes. I let it run until memory exhaustion, at which point TB had eaten 54 GB of virtual memory.

Yes, I have filters, a few dozen simple rules gathered over the years.

Logging will have to wait until tomorrow.

(In reply to Jarkko Hietaniemi from comment #22)

After some downloading and testing... it was definitely the 75.0b1 that brought the issue (and the 75.0b2 still has it). The 74.0b2 and couple of earlier ones I tested do not have it. At 5 minutes after starting Thunderbird, the CPU spikes and memory starts going fast. Attaching some logs soon.

To revisit this comment briefly - 74.0b2 and earlier definitely do NOT have the problem ??

Still needs more information

Jarkko,
Which release are you running now without problems?

Summary: Thunderbird/Mac in startup eats gigabytes of memory and hangs (one pop account) → Thunderbird/Mac in startup eats gigabytes of memory until OOM and hangs (one pop account)

68.10.0 is the safe release.
