I would not call that an error. Nothing is wrong. It's just that
bacula does not have any usable media available.

Do you already have 65 volumes allocated in the pool?

Wait a minute this has to fail. I mean you said you do 100 backups in
12 hours but then your configuration has use the volume once (and hold
each volume for 65 days after using) so that at maximum 65 jobs can be
run without you labeling more volumes manually since bacula will not
label more than your 65 volume limit.
