    Although this issue has been discussed so many times in these forums and I suggest you search. Possible Causes of High Server Loads
    - High server loads could be caused by just one or several resource-intensive application(s). Examples include very high-traffic Web sites, database-driven Web sites, forums, gaming sites, file download sites and so on.

    - A high server load can also be caused by a malicious script or a "runaway script" which can continously loop, dragging down the server's resources.

    - Too many websites on the one server - with the cumulative resources resulting in high server load.

    - Running out of memory and swapping to the swap file.

    - Server backups or server updates are taking place.

    - Misconfigured software causing errors.

    - Users sending large mailing lists.

    - Users trying to bounce spam.

    - Users/spammers sending spam email.

    - Hardware issues including memory leak, bad hard drive, and network card.
