    On one of my cPanel/WHM servers I have a huge problem with PHP. Multiple times a day, the serverload is going to 45.00 / 50.00.

    Some body told me downgraded the kernel to 2.6.9-5, all of problems maybe fixed.

    But how to downgraded the kernel to 2.6.9-5 ? (step-by-step)

    My Kernel current version: 2.6.9-22.EL

    change /boot/grub.conf to

    # grub.conf generated by anaconda
    #
    # Note that you do not have to rerun grub after making changes to this file
    # NOTICE: You have a /boot partition. This means that
    # all kernel and initrd paths are relative to /boot/, eg.
    # root (hd0,0)
    # kernel /vmlinuz-version ro root=/dev/hda7
    # initrd /initrd-version.img
    #boot=/dev/hda
    default=0
    timeout=5
    splashimage=(hd0,0)/grub/splash.xpm.gz
    hiddenmenu


    default=1
    which is the earlier kernel 2.6.9-5

    and reboot yr server

    or update your kernel to the latest 2.6.9-34 ?
