We are running ADSM on a VM server.
We received the following messages for the first time this past weekend.

 ANR9999D SSUTIL(793): LOCK ACQUISITION (SIXLOCK) FAILED FOR SS UNIVERSE LOCK.
 ANR2033E UPDATE DEVCLASS: COMMAND FAILED - LOCK CONFLICT.
 ANR9999D SSUTIL(793): LOCK ACQUISITION (SIXLOCK) FAILED FOR SS UNIVERSE LOCK.

 ANR9999D SSUTIL(793): LOCK ACQUISITION (SIXLOCK) FAILED FOR SS UNIVERSE LOCK.

At the time, two things were going on:
1) QUERY CONTENT of each tape in our library was running to collect information
2) an UPDATE DEVCLASS command was being issued.

Anybody familiar with this problem?    Does IBM know about it?
thanks .. joe.f.
