Why is my Minecraft server crashing?
Minecraft servers often crash due to low amounts of RAM used by your OS. If you are using Windows to host your Minecraft server, reserve at least 4GB of RAM for your system.
As Windows is resource extensive, you should not allocate all of your RAM to your server. If you wish to allocate more RAM to your server, use a different OS such as Linux. It requires only 512MB of RAM to keep your system running smoothly.
