Pidgin taking 100+% CPU at random times

[Daniel McAloon]

Binary package hint: pidgin

Installed: 1:2.6.2-1ubuntu7

Support thread on the forums:

Problem summary: After roughly 18 hours of running pidgin, CPU use goes to 100+%. A single pidgin process can be using up to 190% CPU on a dual-core machine. Problem seems to be temporarily fixed by reboots.

Long version:
A few days after upgrading to 9.10 from 9.04, pidgin began using 100+% CPU. Re-installing libpurple and rebooting seemed to fix it, but then the problem returned. Re-installing ATI drivers seemed to fix it, but then the problem returned. After 18 hours of running (I leave the machine on at night) pidgin will begin taking 100+% CPU. It continues responding at this time, and I can use it (rather smoothly, actually), but everything else is fighting for CPU time. Killing pidgin obviously fixes this issue. I can safely reload pidgin and browse my buddies without introducing the CPU load. I can open new chat window without incident. Sending the first message to the other person will immediately peg the CPU. This is only the case if the machine has not been rebooted recently (apparently).

You should have crash reports attached to this bug, but launchpad was down when it first attempted to load, so if not let me know and I'll re-gen.

Plugins don't effect the issue either, it manifests with all plugins off.

I don't actually have the machine anymore that was causing this issue (it
was a work box and I've switched jobs). After the upgrade to 10 beta the
issue resolved itself, I forgot to close the issue.

There is a new, unrelated bug that I'm going to file, but I won't reuse this
ticket for that.

Thanks,
Daniel
