I have several wordpress sites but for some reason the http://www.newcastleac.org site that I run is causing a bizarre issue. It seems when you log in as admin that there is a huge spike in CPU usage - also over a period of 2/3 weeks it must be keeping threads open as Apache crashes due to memory resource issues. I have 3 admin users on this site and a few plugins.
Any ideas on where to start looking first??
Thanks
