I have a new windows server 2008 R2 with groupwise 12 loaded on it. Every couple of days I have to reboot the server because groupwise quits responding. I look in the event viewer and see this error.

Faulting application name: gwpoa.exe, version:, time stamp: 0x4f153311
Faulting module name: gwenv1.dll, version:, time stamp: 0x4f15311c
Exception code: 0x80000001
