Hi,

We had a similar problem with bacula 3.0.3.
Since I changed a little bit my schedules, the problem seems to be solved.

So perhaps can it be because there are to many jobs scheduled for the same 
time.

[Bacula-devel] bacula-sd deadlock






Hi List,

All most every night our storage daemon get stuck in a deadlock or 
something. In every case only a restart of the storage daemon is the only 
way to get the sd back to work.

This is the case:

We have 2 pools:

Diskpool: contains disk backup volumes.
Migratepool: contains the tape autochanger

Every night between 17:00 and 6:00 the backups (150+ systems) are made to 
the diskpool.
Every day between 11:00 - until ready, all the backups made to the 
diskpool are copied to tape using a copy job. 
 
At night some of the clients are set to make a backup directly to the 
migratepool. This are jobs with a large amount of data (200Gb +)
In other words, at night backups are made to diskpool and migratepool at 
the same time.

Most of the time the copy jobs (to migratepool) are not ready before he 
starts with normal backup jobs (to diskpool or migratepool).

Normal this is no problem, bacula first makes normal backup jobs, and when 
ready he goes further with the copy jobs.

But in our case this results in a deadlock.

Do you have a suggestions to make this better and avoid deadlocks? What 
can we do? Our bacula server is busy 24x7 make backups and copies.

We are using bacula 3.0.3 and debian 5.

Best regards

Jan Jaap Scholing
