Application: akonadi_imap_resource (4.8) KDE Platform Version: 4.8.4 (4.8.4) "release 7" Qt Version: 4.8.2 Operating System: Linux 3.4.3-30-desktop x86_64 Distribution: "openSUSE 12.1 (x86_64)" -- Information about the crash: - What I was doing when the application crashed: The system had a longer period of high network load that lead to several timeouts of different applications. The system runs fine otherwise. I restartet the akoadi server and retried, it appears the crashes can be reproduced. I will try to restart the whole system in a minute. The crash can be reproduced every time. -- Backtrace: Application: c-r.info of type IMAP E-Mail Server (akonadi_imap_resource), signal: Segmentation fault [Current thread is 1 (Thread 0x7f8b7a7fd760 (LWP 31732))] Thread 3 (Thread 0x7f8b69228700 (LWP 31851)): #0 0x00007fffc0dff82f in clock_gettime () #1 0x00007f8b74df3d9a in clock_gettime () from /lib64/librt.so.1 #2 0x00007f8b79bb7014 in do_gettime (frac=0x7f8b69227bc8, sec=0x7f8b69227bc0) at tools/qelapsedtimer_unix.cpp:123 #3 qt_gettime () at tools/qelapsedtimer_unix.cpp:140 #4 0x00007f8b79c8e59d in QTimerInfoList::updateCurrentTime (this=0x7f8b64002860) at kernel/qeventdispatcher_unix.cpp:343 #5 0x00007f8b79c8e8d3 in QTimerInfoList::timerWait (this=0x7f8b64002860, tm=...) at kernel/qeventdispatcher_unix.cpp:450 #6 0x00007f8b79c8d30c in timerSourcePrepareHelper (src=<optimized out>, timeout=0x7f8b69227c9c) at kernel/qeventdispatcher_glib.cpp:136 #7 0x00007f8b79c8d3b5 in timerSourcePrepare (source=<optimized out>, timeout=<optimized out>) at kernel/qeventdispatcher_glib.cpp:169 #8 0x00007f8b74b433ce in g_main_context_prepare () from /usr/lib64/libglib-2.0.so.0 #9 0x00007f8b74b43bcb in ??

I tried these steps, none of it fixed the problem: - restart agent - restart akonadi server - restart the system - remove and readd the imap ressource The resource always crashes after a few minutes. Nevertheless it does report and fetch old and new messages. The resource is therefore unusable: this is a BLOCKER.
Surprising enough I got that issue fixed by restarting the imap server ! It is a cyrus imap server in version 2.3.16. Since that restart I did not experience a single crash anyone.
Unfortunately I have to report that the issue is _not_ fixed. It appears the ressource still crashes, but not in all situations. I will keep an eye on that (cannot really miss it, error popups every few minutes). I got the impression these crashes happen when there are latencies in the network connection.
*** This bug has been marked as a duplicate of bug 301825 ***
Additional information: I fixed a problem on the imap server (cyrus-2.3.16), an invalid 'Trash' folder Wherever that came from (akonadi?) this fixed most of the problems for me. I do not experience any more crashes, though the imap resource is pretty slow (unresponsive) right now. This fits to what I saw in the mail client: diggin deeper I saw a message about a "non existing job" being queued.
