It is very practical for Ram exploitations, I highly recommend it to all Networks, it gives security to know that your server will not suffer any mishap when the Ram exceeds its capacity.
This plugin was not working on previous relases, but now works perfectly. It is useful when your server's RAM use is almost at the limit to safely restart the server and don't have problems or lose data.
This plugin is great for doing a pre-generation on a map, and every time it was rendering and it lowered the chunks per second, and hit the RAM limit it restarted and didn't lose performance so much, thanks for this plugin
