Unless the system is used for kernel development or testing, there is little need to run the kdump service.Solution
Configure OL 9 to disable and mask the kdump service.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
