Tried disabling APF with no success, still the same issue.
Stopped mysqld service (didnt think would make a difference but thought I better try) and again, no difference.

Stopped httpd service, and voila, no more ping problems. So it def seems like its the number of connections coming from Apache that are causing the issue.

Im going to look into apache optimization for now but if you have any quick tips I would apreciate it!

Also see my top output

The number of httpd connections can vary dramatically from 1 to all that you can see above, which shoots up the amount of processor being used.
Should this be happening?
