On a customer's OES2 server, I have started seeing "MPK Anonymous" and "MPK
Thread" processes taking up virtually all CPU time, effectively making it
impossible to run anything else. It started a few days ago even though
nothing was installed. If I restart it, all is fine for about 2 hours and
then these processes come back again. I have searched everywhere for any
hint of what could be causing this, but have found nothing at all. Note
that other OES2 servers in the tree have no issues.

Does anyone have any suggestions?
