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

  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

  The given log doesn't show much information. can you give the following, 1) Are you on a VPS, if so what technology 2) Can you give your server hardware specifications ? 3) What is the disk I/o ?

  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

  Can you tell me how I can check them all ? I need the instructions.

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