We have been running GW 8.0.2 on Linux and GMS with no problem.
After we installed Data Synchronizer POA crashes all the time. Now we have inactivated Data Synchronizer for the time being.
Any ideas?

We have read the Groupwise 8.0.2 Issues:

5.9 Unresponsive POA SOAP Threads

Under certain circumstances, POA SOAP threads gradually become unresponsive, and additional SOAP threads start, building up to a total of 80 threads. Occasionally, the POA crashes as a result. If this occurs, restart the POA.

Shall we wait for an upcomming patch?
