Information

Kernel core dumps may contain the full contents of system memory at the time of the crash. Kernel core dumps consume a considerable amount of disk space and may result in denial of service by exhausting the available space on the target file system partition. Unless the system is used for kernel development or testing, there is little need to run the kdump service.

Solution

Disable and mask the kdump service on RHEL 9.

To disable the kdump service run the following command:

$ sudo systemctl disable --now kdump

To mask the kdump service run the following command:

$ sudo systemctl mask --now kdump
