Hi,
        I have a TL-2000 tape changer with two drives.  I have two differential 
jobs which start at the same time, on different 
filesystems but the same client  (also happens to be the same server as the 
director/storage daemon).  This is bacula 5.0.0

Both jobs interleave to the same tape (this is good IMO, although I don't know 
which knob I tweaked to make that happen 
:)), but one of the jobs first seems to claim a second tape, purge/recycle it, 
log the following rows in jobmedia:
jobmediaid | jobid | mediaid | firstindex | lastindex | startfile | endfile | 
startblock | endblock | volindex
------------+-------+---------+------------+-----------+-----------+---------+------------+----------+----------
       12953 |    38 |       7 |          0 |         0 |         0 |       0 | 
         0 |        0 |        1
       12956 |    38 |       8 |          1 |        37 |         0 |       0 | 
         1 |    14325 |        2
       12957 |    38 |       8 |         37 |        50 |         1 |       1 | 
         1 |    15499 |        3
....

where mediaid 7 is the tape it just recycled and didn't use, and mediaid 8 is 
the tape it's sharing with the other job.

I'm happy for it to interleave, but I'm curious as to why it touches that first 
tape (7) but then decides not to use it. 
   It's effectively recycling/nuking a backup that doesn't need to be, 
requiring two tapes where one will do.   Anyone 
got any idea what's going on?  Happy to file a bug if it is one, but don't want 
to false report.

Thanks,
