Happened to vpn in over the weekend & notice my oes11 servers were all
running very high cpu utilization.

Common thing running high on them was mono. Did a *little* checking,
but could not find much info aside from rebooting servers, so I
rebooted them.

They seem fine so far now, but wondering if anyone has any idea what
caused this & what can be done to keep it from coming back.

Running oes11, fully patched.
