I originally sent this message last week.  Our email system was unavailable
over the weekend and I wasn't sure if anyone responded.  Any help would be
appreciated.

AIX 4.1.3
ADSM 3.1.1.5
9710 STK SILO with Quantum Drives with DLT tapes
Library at microcode level 70
Fast drive load option enabled.

When I receive an I/O error on a tape drive the process hangs.  I can't get
the process canceled which is currently running.  After many hours the
process finally releases the tape drive and I can access the drive again.
Any suggestions for what I can try would be appreciated.
