Roger,

I suspect that your high load may be related to the amount of memory
you have in your system. Your output from top shows that you have
approximately 130MB of swap in use.

You may want to run vmstat or iostat to see how often your server is
hitting disk. If you are not familiar with vmstat or iostat, please
take a look at <http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/admin-guide/s1-resource-rhlspec.html>.

You may need to add more RAM to your server to reduce load/swap memory usage.
