This is a simple plugin designed to help prevent your server crashing with out of memory errors. Every 10 seconds the server will check how much free RAM the JVM has left. If it's below an amount defined in the config, the server will automatically restart.
minimum_ram: 256 # Restart the server if below this amount of free RAM.
tries: 2 # Number of times to check free RAM before restarting. If under the minimum_ram two times, restart.
You need need to use one of these startup scripts: Linux | Windows
Even easier then! Most control panels (MutliCraft and TCAdmin anyway..) will automatically restart the server if it's stopped from outside their control panel. So you should be fine.
