1950332 - Thunderbirds randomly hangs at nsMsgDatabase::OpenMDB for 10 - 30 seconds and continues to work

Status: UNCONFIRMED

(MailNews Core :: Database, defect)

Description

[Wolfgang Marx]

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/133.0.0.0 Safari/537.36

Steps to reproduce:

I have the issue, more or less permanently, that Thunderbirds crashes all the time during my normal working hours. Never mind if running in troubleshoot mode or default.

I already created:

a) Created the IMAP Files new
b) Cache relocation to RAM
c) Profile is running on an NVME
d) deactivated add-on
e) many other things I tried.....

It happens out of a sudden, it just crashes - for 10 - 30 seconds and continues to work. Sometimes 4-5x per hour and then only once on one day. I have no idea anymore. Can I not create a crash report and share it here somehow?

On weird thing. I copied the profile to my second Personalcomputer, a windows 11 machine and with the same profile and settings - Thunderbird does not crash, it was running for days with my Thunderbird Linux profile. Working with Windows is no solution - it was just for the purpose of testing.

Actual results:

Thunderbird crashes

Expected results:

Thunderbird should be able to run smooth and stable within the given configuration

Do you have anything at coredumpctl?

Thanks.

That's a hang, not a crash.

I have executed the steps to debug, hopefully there is something useful.

Took this one:
wmarx@tux:~$ coredumpctl list | grep thunderbird

Thanks

Wolfgang, does the Thunderbird crashes (i.e. whole application vanished and you need to start it again) or do you see just a freeze? I.e. you can't interact with the application but it stays on the screen and it works again after a while?
Thanks.

Right, absolutely, it hangs for 10 Seconds, sometime for 30, not really predictable - and after a while it starts working again. Incredible annoying and bothering during working hours. Then I would almost prefer a crash, not a hang.

Please try to get backtrace if you see the freeze.

1. Install TB debuginfo packages and gdb debugger on terminal:

# dnf debuginfo-install thunderbird
# dnf install gdb 

2. If you see the freeze, attach gdb to it. Run on terminal:

$ gdb thunderbird `ps ax|grep thunderbird/thunderbird|grep -v grep|grep -v "contentproc"|cut -d ' ' -f4`

3. Print backtrace (by bt command) and attach it here:

(gdb) bt

Thanks.

Hi, I did print the bt but can find it on my fedora machine - in which directory is the the file supposed to be? And abviously I cannot do any uploasd here means I have to share a google link or something similar, haven't I?
my best

You need to issue the bt command from inside gdb debugger, which is launched in the second step. bt command prints a backtrace on terminal so please copy it there then.

Looks at https://www.youtube.com/watch?v=8AHT8uJX38k for instance how debugging in gdb looks like.

[Wolfgang Marx]

Ok, got it, so have to wait until the next hang. Thanks

Looks like an issue with processing TB database:
