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.
