That one is easy, and not very interesting actually. The two most
frequent causes are:
a) network outages (we do some backups over WAN VPN connections)
b) clients crashing during backup, either coincidentally or because the
additional load from the backup pushes an already flakey machine over
the brink.
Neither is Bacula's fault, and therefore something that would warrant a
Bacula bug report I think.
(Although I do sometimes wish Bacula would handle clients disappearing
in the middle of a backup more gracefully.)

To sum it up: there can be legitimate reasons for a job not terminating
successfully, but that shouldn't lead to a diminishing maximum spool
size IMHO.
