    I'm got two dedicated servers with WHM set up. Server software is very similar on both, and both are up-to-date with WHM. One of them has had a few quirks lately, the latest of which is a required reboot for kernel upgrade. We had been managing kernel upgrades with Ksplice and haven't updated the running kernel since that went away.

    Following the WHM 64 update, I installed KernelCare on one of the servers using the Ksplice to KernelCare migration script. Appeared to go fine, and Security Center sees it and says we're on kernel 2.6.32-673.26. However, I'm still getting the alert in the top right saying "You must reboot the kernel to update kernel." I checked uname -a on the shell, and sure enough I'm getting an older version: 2.6.32-531.17.

    What's needed to get the proper kernel running? Is there a way to avoid a reboot? And why is Security Center reporting a different version than uname?

    Hello,

    The following case was included with cPanel version 64.0.7:

    Fixed case CPANEL-12259: Avoid mistaken reboot suggestion on KernelCare systems.

    Could you verify what version of cPanel is installed on this system? EX:

    Code:
    cat /usr/local/cpanel/version
    Thank you

    Running 64.0.18, with the reboot message still showing and uname still showing a different kernel version than the security advisor.

    Could you open a support ticket using the link in my signature so we can take a closer look? You can post the ticket number here so we can update this thread with the outcome.

    Thank you.

    Hi,

    Make sure /boot/grub/menu.lst has newest kernel active
    and then reboot. That should fix

    Thanks,

    Hello,

    To update, the following case in cPanel 64.0.22 should address this issue:

    Fixed case CPANEL-12778: Silence reboot warning when Cpanel::Kernel::Status changes.

    Thank you.
