    Hi all I have been noticing over the past several days that my server is running high cpu loads.
    It seems mysql, nobody, and mailman takes a lot of resource.
    Anybody help me ?

    Here is my top -c
    Code:

    Hi,

    You can check the MySQL process using below command so that you will get idea which database causing the high load.

    [root ~ ]# mysqladmin proc

    Vinzleon,
    Looks like hardware configuration is normal. Now you need to do check the following ,
    1) Mysql usage during the load time
    2) apache usage during the load time
    3) Disk I/o during the load time
    4) Check if any backup is running on that time

    You can review the URL that I posted in my earlier response for information on how to obtain those values.

    Thank you.
