WHM shows that a reboot is required when KernelCare has been installed

Symptoms

With KernelCare installed, you may find that the WHM Security Advisor reports the following warning:

CONFIG_TEXT: Update the system’s software by running ’yum update’ from the command line and reboot the system.

WHM will also display the following message:

CONFIG_TEXT: You must reboot the server to apply software updates.

Cause

KernelCare prevents the need to reboot only when kernel-related packages are updated. Some system packages, such as systemd, still require a reboot after updating.

To review which packages require reboots for updates, you may execute the following command via SSH when logged in as root:

# needs-restarting -r

Resolution

Reboot the server.
