    Daily Process Log, i already repair and optimize all table, like you can see the mysql process is very low (in white line, not in yellow or red line), so its looks like the problem is not in mysql
    The red line is maybe apache







    Nb1. I use a dedicated server, only host 1 site, here is my server specs
    Intel Single Xeon E3110 3.0ghz L2 cache 6MB
    Memory 4 GB DDR2 RAM
    Harddisk 500 GB Sata 7200rpm
    Cent OS 5.4
    WHM/Cpanel


    Nb2. I already check no backup/cronjob or related scheduled active right now


    Nb3. I already disabled the feature one by one, Even i already block all search engine spider now using robots.txt disallow for 2 days, no spiders again in my website until the problem found, its ok i just need to found the source problem


    Nb4. I dont think my hosting support can help it, and they cost very expensive for that extra managed service ($69/hour), i want to find the source problem by my self, please analyze and give advice to found the source problem

    It will be easier to find the problem for your hosting support since they can login to the server. I've seen this many times.

    Try:

    ps aux|grep exim
    If there are many, check the mail log

    ps aux|grep httpd
    If there are many, check the apache log

    Also check Apache Status

    Your script or server could be hacked.
