[Bacula-users] Pretty serious bug just discovered

I have been having crashes with the latest version of Bacula director (v7.0.5-1 
x86_64 from slaanesh repo on RHEL6) off and on and just discovered what was the 
sequence of events that is causing the problem.   If there is an incremental 
job currently running and the same job is started as FULL or Differential 
backup, the incremental job is terminated, however the director suffers a 
segmentation violation and crashes.  It is repeatable.  I'd had a director 
crash over the weekend just as my FULL backups were queuing up, so I'd been 
manually starting smaller groups of those jobs each day to allow my daily 
incrementals to process.  I did not check to see that the FULL job that I was 
starting this morning already had an incremental job in-progress and then my 
director was dead.  So, to test, I started an incremental job, let it run for a 
minute or so and then started the same job as a FULL and down the director went.


The following is from /var/log/messages


Jan 28 08:55:57 back1 bacula-dir: Bacula interrupted by signal 11: Segmentation 
violation

Jan 28 08:55:57 back1 kernel: bacula-dir[18973]: segfault at 0 ip

Jan 28 08:56:04 back1 bacula-fd: bsock.c:427 Write error sending 199 bytes to

I will be opening a bug report shortly.
