Well one of my FreeBSD 9.2 systems decided to take a new route to this
problem. My backups starting failing this morning, without the
bacula-fd process stopping, it starts the client run before job script,
then after two hours fails with no response from the client.

When I check this server, the client run before job script completed,
all the database dumps, were successful, and the ZFS snapshots that
follow the Database dumps complete as well. However Bacula stops
returning the script's status.
This server was running fine on up through the full backup done Monday
morning, but now comes right back to this problem on every attempt to
backup today. A reboot didn't help, trying a full backup instead of
incremental made no difference.
Canceled one of the attempts, and restarted after removing the client
run before script, its now backing up files just fine. so I have
temporarily setup a cron job to run 30 minutes before backup to execute
my database backups and zfs snapshots. and removed the client run
before job.
I can find no errors logged on the server running the bacula-fd or the
bacula server with the exception of the timeout error message. Tried
adding heartbeat interval of 1 minute on the client, that didn't help
either.
