The environment:  NBU 4.5GA MP2 on Win2K Svr SP3, 2 Win2K DC SP2 media
servers, STK 9840 drives on a SAN using SSO.

Has anybody ever seen this error message:  Compression unlock 336 failed:
The handle is invalid. , (6)?  There are lots of these messages from the
master server in the all log entries report, and there are several different
3-digit numbers after compression unlock (not just 336).  I upgraded to 4.5
last night, and had just gotten all the problems ironed out when this
started.  Stopping and restarting all NBU services didn't solve the problem,
but a reboot did.

Thanks,
Matt
