Application: kontact (4.8.0) KDE Platform Version: 4.8.00 (4.8.0 Qt Version: 4.7.4 Operating System: Linux 3.0.0-15-generic x86_64 Distribution: Ubuntu 11.10 -- Information about the crash: - What I was doing when the application crashed: Upgraded the kubuntu KDE packages, and since then kmail alwasy crashes some seconds after the window appeared. I did some runs under "strace kmail --nofork", and it appeared as if the process is running out of file descriptors. Increased the ulimit, and voila, still a crash, but a little later. Will add some more information in a moment. The crash can be reproduced every time. -- Backtrace: Application: Kontact (kontact), signal: Aborted [Current thread is 1 (Thread 0x7ff5f52a27a0 (LWP 8964))] Thread 4 (Thread 0x7ff5dac43700 (LWP 8965)): #0 pthread_cond_wait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S:162 #1 0x00007ff5f1afac2c in ??

I increased the limit to 16384, and then the crash would look similar, with the last line reading close(16384) = -1 EBADF (Bad file descriptor) May be related, the trace is full of messages like recvmsg(3, 0x7ffffd5c88b0, MSG_CMSG_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) maybe that's the reason it's running out of descriptors? Of course, it's very annoying not being able to start my main mailer :-(
