The server load is extremely high. I'm trying to diagnose what's going on. Screenshot attached.
edit: OS is CentOS 5. Not running anything like plesk or cpanel, etc.. The raid10 has 1 failed drive, the other 3 are good. It will be replaced soon. There have been no traffic spikes. The server load is usually in the 3-4 range. We added 4GB more, but no change. It is a physical server, yes. If apache is stopped the load is less than 1.0 yes.
