i just restarted the sd and dir daemons after the config change

for 'show dir', i get:
Director: name=uwharrie-dir MaxJobs=20 FDtimeout=1800 SDtimeout=1800
query_file=/etc/bacula/query.sql
--> Messages: name=Daemon
mailcmd=/usr/sbin/bsmtp -h localhost -f "(Bacula) %r" -s "Bacula
daemon message" %r

for 'show storage', i get:
Storage: name=Autochanger address=uwharrie SDport=9103 MaxJobs=4
DeviceName=PX502 MediaType=LTO-3 StorageId=3

wow... i think you nailed it... i am using different job priorities for
each job... and that would explain the fact that bacula has only been
running simultaneous jobs of the same priority level for me... i will
test this asap...
so, i should set *all* jobs to the same priority? or should i just set
the backup jobs as "Priority = 1" and restore jobs as "Priority = 2"?
thx in advance,
mike
