I'am using Wordpress 2.9. Webserver 8GB from Hostgator.
I'am fighting with this problem for long time but still can not find the solution. Php switched to run as an apache module, Php 5 in DSO, Apache suEXEC, eaccelerator installed, but this configuration started making huge server load on server.
Server load spiking from 1 to 250 (4 cpus) and server stops, after period of time its back again and stops in about 10 minutes. It started happening when hostgator support team installed eaccelerator on server. What can make this problem and how can I fix it?
