Thank you
Using the tool "atop" you can find out which process is using so many resources and which resources exactly. High system load can be caused by CPU or disk I/O overload.
If it's an FCGId process, the user under which it runs will tell you which website is responsible. You can then check the Apache logs for anomalies, like spiders flooding the site with requests (happened to me several times lately). I now use mod_qos to mitigate rampant robots.
