We recommend that you restart your Minecraft server at least once every day.
This provides benefits such as allowing the RAM used by Minecraft to clear our useless and old data from when your players disconnect, chunks, entities, etc. Restarting once every 12-24 hours will make sure that you have little to no lag from overuse of RAM.
To setup automatic restarts on your Minecraft server, you can check out our Knowledgebase article found here.
