You said you get 60k to 80k hits/hour some times, and this is eating
your memory away. If you have Apache or IHS installed, you should
consider taking a look on httpd.conf to reduce the webserver memory

By default, the httpd.conf loads a whole bunch of modules, for

Are most of them from one server?
