[Bug 1026680] [NEW] bacula director crashing whole system

[Thomas Schweikle]

Public bug reported:

I've installed bacula-fd, bacula-sd, bacula-director, and bacula-console on an ubuntu 10.04 system. Bacula working with an PostgreSQL-Database. Upgrading from 10.04 to 10.10, then 11.04 and 11.10 didn't reveal any problems of unstability of bacula or postgres. After upgrading to ubuntu 12.04 LTS the system started to crash randomly.
At now I am not able to finish even only one backup cycle without bacula crashing. The host runs, but isn't reachable any more over the network. Trying to log in at console lets me type username and password, but after successfully logging in, I am immedeately logged out again. Running a shell on a terminal directly doesn't work either: if it is started on tty12, you may switch to tty12, but no keypress accepted – the shell is dead.
Pinging the server will timeout. The only way to recover: reset it, or, if impossible, power cycle. The system will start again bacula running, but all logs truncated, because of file-system repairs and log replay. No messages telling about why the system crashed.

While bacula runs fine doing nothing, it does run fine too, backing up
only a few system, it starts crashing backing up lots of systems with a
realy huge database. I assume the problem exists with the database
exceeding some size, but, since the logs truncated until the last
commit, I do not have any information about what part of the system ist
resposible for the crashes.
