Thunderbird freezes on dual core system

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at [WWW] https://wiki.ubuntu.com/Bugs/FindRightPackage . I have classified this bug as a bug in mozilla-thunderbird.

Is this symptom still reproducible in 8.10?

I don't know if it's reproducible in 8.10. My work desktop has been running 8.04 (2.6.24-21-generic) for some time, and Thunderbird (now 2.0.0.17) still freezes regularly. I can't upgrade to 8.10 yet because this is a production machine which I depend on at work, and I don't have any other similar hardware available to do testing on.

I am unable to reproduce this on Intrepid and im running 256 ram and p4
1.7ghz However i doubt this is a processor issue. Can you please
disable all you plugins/addons/extensions and try it again. Also look in
top when tbird locks up and see what the top process is (it will change
but look at CPU usages) Let us know what you find.

Hi, John -- Thanks for your comments.

I tried changing the way I launch Thunderbird. Instead of invoking the executable directly, I am now exec'ing it from a shell script that captures any output into a log file. After I did this, Thunderbird courteously obliged by freezing :-}, and I got the following error:

*** glibc detected *** /home/richw/lib/thunderbird/thunderbird-bin: malloc(): memory corruption: 0xaad841a0 ***

plus a backtrace and a memory map, which I'm including here as an attachment.

Since this is my production work environment, I really can't "disable all plugins/addons/extensions" without creating what, for me, would be an unusable setup. If there's any way at all to use the error output I just got to identify any offending add-on, that would be very helpful to me in this situation.

I started having these exact same symptoms only *after* I recently upgraded to 8.10 on an AMD dual-core. On 8.04 on the same computer, thunderbird did not habitually freeze. This is extremely annoying and damaging to productivity as well -- please contact me if there's any way I can help.

I've attached my terminal output too.

Is this an issue for anyone using the official thunderbird package from the Ubuntu repos?

Hi,

It is an issue for me using official thunderbird from the repos on a 8.10. Thunderbird eats up memory and CPU after some time.

See top output below.

@Antoine
Does your thunderbird freeze? Do you have a dual core system? This bug is about thunderbird freezing on a dual core system.

@Micah
- yes I have a dual core system ( model name : Intel(R) Core(TM)2 CPU 6300 @ 1.86GHz)
- thunderbird "nearly" freezes....which means it still responds but it would take about a min. just to redraw an email window.

Intrepid comes with 2.0.0.17 and provides 2.0.0.21 as an update. Can you please tell us which version you are running or paste the results of:
apt-cache policy thunderbird

Also, do you have any extensions installed? A lot of times extensions can conflict with each other and cause problems.

# apt-cache policy thunderbird
thunderbird:
  Installed: 2.0.0.21+nobinonly-0ubuntu0.8.10.1
  Candidate: 2.0.0.21+nobinonly-0ubuntu0.8.10.1

add-ons:
ImportExportTools 2.2
Remove Duplicate Messages (alternate) 0.3.2
WebMail 1.3.2
WebMail hotmail 1.2.22

Could you please try with the extensions disabled to see if the crash still occurs?

@Micah: TB running now with extensions disabled, I'll post a report here in a couple of days

Hi,

I add to upgrade my system to 9.04, and for your info TB doesn't freeze any more.

@Rich Wales
