    How do I know when I need to upgrade the kernel? Seems cpanel doesn't do this automatically.

    Depends on your OS and how you have the OS vendors update app configured. What OS are you running?

    Running Linux.

    I'm not sure what you mean by "how you have the OS vendors update app configured."

    Can you be more specific?

    The OS will have it's own system for updating software, independent of cPanel.

    Indeed. We'd need to know the exact OS and revision that you are running. If it's a RedHat derivative you can usually get all the information you need from:

    cat /etc/redhat-release

    Also the output from the following would help:

    uname -r

    Running "up2date --force kernel" should do it, but be sure to use kernel-smp if you have a multi-processor system. Reboot once up2date is done. You may also need to edit grub.conf to make it boot the new kernel by default, I can't remember if up2date does that for you or not.

    Thanks Chirpy.
    You are great. But sometimes you are too technical and don't realize that you know so much more than we do and we can find it hard to follow sometimes :)

    Red Hat Enterprise Linux ES release 3 (Taroon Update 4)

    2.4.21-32.0.1.ELsmp

    You are running the latest kernel for RedHat Enterprise v3.
