This looks similar to a problem I encountered.

There's some locking problem in the SD which can be triggered when you 
have many jobs running simultaneously. I usually encountered it when 
Jobs were waiting for volumes from another pool.

The only workaround possible is to make sure you have the necessary 
volumes available before the jobs start (which can be hard or 
impossible, depending on your autochanger capacity and the amount of 
data to store).

After the usual sequence of unmounting, changing tapes, 'update slots' 
and mounting I saw what you describe - unknown system jobs blocking the 
device.

Upgrade to - at least - 1.39.30something, I believe. Kern included a fix 
for this problem, and I did not encounter it afterwards.

Off course, today you should upgrade to 2.0.

There is no possibility to unblock the SD that I know - I always had to 
restart the SD, restart the affected jobs, and thus do things manually 
that should be automatic.

Well, then the upgrade process is definitely preferable :-)
