Description Jure Repinc 2010-12-03 14:59:54 UTC

Application: akonadi_mixedmaildir_resource (0.1)
KDE Platform Version: 4.5.82 (4.6 >=20101201) (Compiled from sources)
Qt Version: 4.7.1
Operating System: Linux 2.6.36-gentoo-r3 x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:
I updated KDE software from 4.5.3 to 4.6 from trunk. When i started KMail it started converting the mail to Akonadi which took a very long time. After that i've closed KMail and then I reopened it and clicked on a mail folder from GMail and then also on a mail folder from local mail downloaded from POP3 server. The process akonadi_mixedmaildir_resource started using huge amount of memory (1 323 256K according to memory column in KSysGuard). After some time I got the crash dialog.

-- Backtrace:
Application: Akonadi Resource (akonadi_mixedmaildir_resource), signal: Segmentation fault

Comment 1 Kevin Krammer 2010-12-03 15:18:18 UTC

From the description of things I can imagine that the resource got killed by the system's out of memory killer.

Can you give me any details on that folder? E.g. if it is mbox or maildir, how many messages it has, etc.

In case you can easily trigger this, could you try to get some of the debug log output?
I.e. enable the resource's debug areas, restarting Akonadi in a Konsole window (probably with increased or unlimited history) by running akonadictl restart

Thank!

I can't get the crash anymore with KDE SC compiled from trunk on 2010-12-18. If I check the Inbox folder properties it says that it KMail Maildir with 34132 messages in 194 MiB. I'll attach the Konsole output just in case.
