I tried posting this with a screenshot but the post didn't come through.

At any rate,

We've got a Netware 6.5 SP3 Virtual Machine running the latest version of VMWare GSX Server (Windows host) with the latest VMWare tools installed. The CPU utilization is pegged at 100%, and a server thread shows up as "Busiest thread" in monitor. How else would I go about finding useful information to see exactly what is causing this issue?

Despite the high utilization, the server seems responsive enough. This occurs after a reboot, as well (and with VMWare Tools unloaded/uninstalled)
