maxvolume jobs is set at 0 for all volumes on the system, as dangerous 
as it is to assume, I assume that means unlimited.  There is already 14 
jobs currently that have been written to this volume that my tests are 
hitting currently, though one at a time.  Of those 14 jobs, there are 
multiple from each of the servers I am testing my backup against while 
working on the concurrent jobs.

None of the client jobs specify any target volumes, only storage and 
pool, both client jobs are set with the some storage and Pool settings, 
in fact the only difference is the names,filesets, and the first job 
does have a Client run before job, and after job scripts.  Fileset 
options are all the same, except the included and excluded files 
entries.


Since I didn't think to mention versions before:
The backup server, (one test client is the backup server itself) is 
running FreeBSD 9.0-RELEASE-P3, with bacula 5.2.10, the file daemon of 
course is 5.2.10 as well both built from the FreeBSD ports system.  
Server is hitting a PostgreSQL 9.1.4 database backend for the catalog 
(is there possibly anything limiting jobs writing to catalog at once 
that I am missing).  second client is actually a FreeNAS 8.2-RELEASE-P1 
with bacula-fd running in a plugin jail on version 5.2.6 compiled from 
the FreeBSD 8.2 ports system within that jail.
