For the most part, this is "esoteric high end use" :-)

I am seeing this too.

Additionally I'm getting multiple-hour hangs when trying "status director" 
in bconsole as it tries to check for jobs waiting to reserve a drive.

The same hangs occur in the tray monitor.


Having observed it for a while, it looks like anything using drive 1 
causes drive 0 to be locked out, but using drive 0 does not lockout drive 
1.


Kern/others: Any ideas?
