I have a 6.5 sp2 server on an HP Proliant DL380 with dual G3 processors -
35 users. The system lists 4 processors (0-3), but I assume this is due to
hyper-threading? Anyway, all of a sudden processor (1) is consistently at
or near 100% utilization (even though Monitor shows the server utilization
at 25%.)

This server as always ran at 0 to 5% in the past. I even unloaded Symantec
Anti-virus and Backup Exec and that didn't help. What is the best way to
see what process or module is suddenly causing this? Nothing in the
environment has changed.

Thank you for your help.
