A NOTE has been added to this issue. ====================================================================== http://bugs.bacula.org/view.php?id=901 ====================================================================== Reported By: wolfmair Assigned To: ====================================================================== Project: bacula Issue ID: 901 Category: Director Reproducibility: always Severity: minor Priority: normal Status: feedback ====================================================================== Date Submitted: 07-20-2007 09:00 EDT Last Modified: 07-26-2007 08:47 EDT ====================================================================== Summary: Fatal Error because: Bacula interrupted by signal 11: Segmentation violation Description: Bacula-dir crashes while atemting to restore a client which can not be contacted. On OpenSuse 10.2 with bacula 2.0.3 # uname -a Linux porsche 2.6.18.2-34-default http://bugs.bacula.org/view.php?id=1 SMP Mon Nov 27 11:46:27 UTC 2006 i686 athlon i386 GNU/Linux ====================================================================== ---------------------------------------------------------------------- kern - 07-20-07 10:02 ---------------------------------------------------------------------- Unfortunately the traceback is unusable because the SUSE kernel guys seem to be unable or unwilling to supply a "production" kernel that works. Output such as "http://bugs.bacula.org/view.php?id=2 0x00000000 in ?? ()" is total nonsense. I'm switching distros because of that. I'll try to duplicate it, but without a good traceback, this will be hard to fix. You might try issuing the following command as root *before* starting Bacula: echo 0 > /proc/sys/vm/vdso_enabled in most cases, it seems to be a workaround that will permit proper debug output. In general any time you get: "Failed to read a valid object file image from memory." the gdb output will contain nonsense for all or part of the traceback. ---------------------------------------------------------------------- wolfmair - 07-25-07 06:36 ---------------------------------------------------------------------- Ok I will try this but it will take some time. At the moment I am stuck with 'File size of restored file not correct...' ---------------------------------------------------------------------- wolfmair - 07-26-07 08:47 ---------------------------------------------------------------------- Ok here we go. It crashed again. Although it crashed this time under different circumstances. The client was reachable but it showed the same behavior. When I start a restore and so a status director right after, it can not list the running jobs and crashes. Hopefully this traceback contains the needed information. Using host libthread_db library "/lib/libthread_db.so.1".
