I am working on a Netware 6.0 SP5 server and have noticed that almost
every night around midnight the Server Health Log show that the CPU
utilization bounced from around 80% to 100% for anywhere from 15 minutes
to a hour and 15 minutes. No backups are being run and the Symantec
virus update is scheduled to run at 12:45 am.

Is there a log file that I can look at that will tell me what is using
the cpu that much?

One other note. I am running Zenworks 6.5 SP2 and inventory is set to
happen only on Wednesdays between 7:30 am to 4:30 pm.

Here is a sample of the Health log from before the problems occurs.
