How I wish I'd never patched GroupWise!!! We were on some form of 8.0.3 for a long time, with little or no issue. But an issue with our GMS server, and the security fixes that I'd avoided for a while meant I moved to 8.0.3 HP4 this weekend.
Since then, the server has been up and down like the proverbial!
It's on NW6.5 SP8, on VMware, so it's as experimental and un-supported as it gets, but it had been fine and stable.

Anyway, the abends all seem to resemble...

Running process: GWTCP-Brig-Handler_10 Process
Thread Owned by NLM: GWPOA.NLM
Additional Information:
The CPU encountered a problem executing code in GWENN5.NLM. The problem may be in that module or in data passed to that module by a process owned by GWPOA.NLM.

I don't suppose I can back rev just the POA agents could I, or do the MTA's share files with the POA?
I'm reluctant to put up with this because it's not viable for me to keep rebooting the server daily, even though the abend lets users carry on working.

TIA, Alan
