Paul, Can you do the following? 1. Upgrade your kernel to the latest RHEL5 kernel. This can be found at http://people.redhat.com/~dzickus/el5/ 2. Attach an sosreport from your system, and, 3. There is a good kernel building benchmark utility called kernbench which is available for download at http://freshmeat.net/projects/kernbench/ Could you run this without any options and send us the output? Thanks, P. Paul, Your "cpu intensive" task, is it memory intensive too? P. |
