I've set up the TKL WP virtual appliance on VMware and put about 15 pages online in Wordpress. There is no traffic on that site yet as it's currently in development and still blocked by a firewall in front from being accessed.
Sometimes performance is just fine, but very often I see apache going to 100% cpu load, no matter what is being accessed (wordpress site, phpmyadmin, webmin).
Except setting an IP address there are no changes yet made on OS level and I doubt it has anything to do with the WP content and plug-ins I added as the issue also shows up with phpmyadmin or webmin.
First thought was a VMware host issue but I moved the VM to another host where it shows the same issue. In addition, all other VMs (Windows and Linux based ones) running on the same hosts have no performance issues at all.
Currently I'm pretty much stuck as I am not sure where and what to troubleshoot within apache to get closer to the root cause.
Anyone with better apache know-how here to give me a hint how to diag what's causing the high apache load?
