I recently upgraded to GroupWise 8. It ran fine for 2 weeks. I am running this on a cluster (fiber channerl SAN). I have two POs. One runs fine. The other will load, but will Abend the server within a few minutes. Here is a general summary of the Abend:

Date of ABEND: Wednesday, July 22, 2009 12:07:25.587 pm
ABEND Reason: Abend 1 on P01: Server-5.70.08: Page Fault Processor Exception (Error code 00000002)
Running process: GWPOA-PO2-Worker_3 Process
Interrupted process: N/A
Thread Owned by NLM: GWPOA.NLM
Stack: --000000B0 (LOADER.NLM|KernelAddressSpace+B0)
--43AE8000 ?
--BBE1DC0C ?
Additional Information: The CPU encountered a problem executing code in LIBNSS.NLM. The problem may be in that module or in data passed to that module by a process owned by GWPOA.NLM.

Any ideas? Thinking of doing an NSS /poolrebuild /purge to see if this helps.
