I have several server in multiple clusters. All of the servers have
IPStor client loaded. For some reason and at night, one of the sevrers in
the cluster ABEND. Here's the abend message:

Abend on P01: Attempt to release an unaquired spinlock OS version: Novell
NetWare 5.60.05 May 27, 2004. Running Process: SANtpRequestThread Process
Stack: E5 FF 12 00 0D 39 11 00 F8 1B 14 00 8A 9B 11 00

Additional info: The NetWare OS detected a problem with the system while
executing a process owned by LOADER.EXE. It may be the source of the
problem or there may have been a memory corrution.

Any clue?
