moved a large POA (801HP1) from Netware to OES2SP2.

Now POA log file shows lot of these errors:
Couldn't log event: someactionmentioned ‑ [8F01]
Error with GWEvent notification [8908]

When looking at POA web console, otherwise normal but I can see SOAP
threads running out / keeping quite busy.
We are running GMS3 and small test of GWMobility.

What to check?
Other POAs are running ok on OES2.
