The reason behind this problem is the services are crashing into a loop and failed to start for some reason. So, despite clearing the PIDs from the system, the daemon will keep restarting the service.
If it is an Ubuntu distribution, please use the below commands to disable the service from getting started automatically.
$ systemctl disable [service-name]
$ systemctl daemon-reload
If it is a RedHat distribution, you may disable the auto-restart by using the below command.
$ chkconfig [service-name] off
