Nepomuk is not available after the crash, even if ps -ef | grep -i nepom reports all nepomuk processes as running. 2093 2049 0 10:30 ? 00:00:01 /usr/bin/akonadi_nepomuk_contact_feeder --identifier akonadi_nepomuk_contact_feeder 2106 1 0 10:30 ? 00:00:00 /usr/bin/nepomukserver 2219 2106 0 10:30 ? 00:00:00 /usr/bin/nepomukservicestub nepomukqueryservice 2220 2106 1 10:30 ? 00:00:26 /usr/bin/nepomukservicestub nepomukfilewatch 2223 2106 0 10:30 ? 00:00:00 /usr/bin/nepomukservicestub digikamnepomukservice 2224 2106 0 10:30 ? 00:00:13 /usr/bin/nepomukservicestub nepomukontologyloader 2225 2106 0 10:30 ? 00:00:00 /usr/bin/nepomukservicestub nepomukactivitiesservice ct529 2226 2106 0 10:30 ? 00:00:00 /usr/bin/nepomukservicestub nepomukremovablestorageservice ct529 3581 3561 0 11:11 pts/1 00:00:00 grep -i nepom Just a note: I have had nepomuk service stub segfault every time I start KDE. I just added "Disable glx" to my xorg.conf file (because it was segfaulting) and now nepomuk is running. This is with the rpm fusion kmod-nvidia driver - which has been suspected in many of the google-chrome and nepomuk problems. Side note - Google chrome runs now also. Marking this to FIXED. I see no evidence of anything Nepomuk related in the backtrace, and the reporter is no longer experiencing the issue. |
Application: nepomukservicestub (0.2) KDE Platform Version: 4.5.3 (KDE 4.5.3) Qt Version: 4.7.0 Operating System: Linux 2.6.32-27-generic x86_64 Distribution: Ubuntu 10.04.1 LTS -- Information about the crash: - What I was doing when the application crashed: I logged into kde, and the nepomukservicestub segmentation faulted. - Unusual behavior I noticed: As of late there has been a lot of hard drive work when I log into kde. It takes several seconds for the disk to stop working. It seems most of the work is done by nepomuk but I am not 100% sure. -- Backtrace: Application: Nepomuk Service Stub (nepomukservicestub), signal: Segmentation fault __lll_lock_wait_private () at ../nptl/sysdeps/unix/sysv/linux/x86_64/lowlevellock.S:97 in ../nptl/sysdeps/unix/sysv/linux/x86_64/lowlevellock.S [Current thread is 1 (Thread 0x7f59cde99760 (LWP 2110))] Thread 8 (Thread 0x7f59b9fad700 (LWP 2117)): #0 __lll_lock_wait_private () at ../nptl/sysdeps/unix/sysv/linux/x86_64/lowlevellock.S:97 #1 0x00007f59cb2bf3dc in _L_lock_12449 () from /lib/libc.so.6 #2 0x00007f59cb2bde78 in *__GI___libc_free (mem=0x7f59cb5bee40) at malloc.c:3736 #3 0x00007f59ca7781ba in ??
