We recommend you stop the OnApp service on your Control Panel server before gracefully rebooting it.
To stop it, send the following command via SSH, logged in as root:
service onapp stop
For OnApp 3.4 and later:
Starting from OnApp 3.4, we implemented a daemon monitoring service called monit. To stop OnApp and make it remain offline, the monit service must be stopped first:
service monit stop
After the monit service is stopped, the OnApp service can be stopped.
