I have a single cpu, rhel es 3.0 u 5 system that shows excessive 'system cpu" utilization. I think, but, am not sure that the httpd process is causing this. Can anyone suggest a method to find out: 1) what process is causing the system utilization to go up 2) what system calls are being made overall and how many of each? Any help or suggestions on this would be appreciated. This is a production system, so rebooting or shutting down processes is not desirable. ------------------ Marvin Blackburn Systems Administrator Glen Raven "He's no failure.
