Starting on August 11, Bacula 3.0.1 suddenly decided that the director needs to crash after it runs random incremental backups and lock up the storage director.  I tried upgrading to 3.0.2 on all clients and directors, but that didn't fix the problem.  The director and storage directors run on Gentoo and the clients are a Gentoo/Red Hat/Windows/Ubuntu mix.  I should mention that I have two storage directors and both exhibit the same behavior.

     For example, I can have Client1, Client2, and Client3.  Incremental backups will run fine for Client1 and Client2, but the incremental backup for Client3 will cause the director to crash.  It also locks up the storage director with a message like "JobId=16459 wants Pool="Client1-Pool" but have Pool="Client3-Pool" nreserve=1 on drive "My-Device" (/bacula/vtapes).

I can fix the issue for the storage director by restarting it, but that's the only way I've found to fix the bacula-sd problem.  I have to restart the director as well because it crashes when this happens.  If I then do a full backup of Client3, it will work and so will subsequent incremental backups.  However, later Client2 will start doing the same thing until a full backup is run.

Any ideas that people can shed on the subject would be very helpful.  Using gdb, I tried to get some debugging information, but it didn't give me anything at all.
