Stupid question but have though about increasing your swap file size.
Best practices is to have a least 1.5 times your RAM anyways.  After you
do this you might find that your limiting factor on the servers is
memory anyways.

Hi

Servers all have 4Gb RAM.  Swap file is 4096 (min and max).  85-95% of
swap 
gets used on all servers.  We will be looking at using Appsense or
TScale 
soon which may help reduce swap usage but for now I need to use the best

evaluators for the current environment

Regards
