node-minecraft-protocol: out of rage error on connection

Start with server.js and the stack-trace entry points in node_modules/minecraft-protocol/src/transforms/framing.js and node_modules/protodef/src/datatypes/varint.js. Use the logged malformed packet and ERR_OUT_OF_RANGE failure to investigate why the server process exits; done means malformed connection input no longer crashes the server.

Server crashed because maybe a player or bot spam send something on port 25565 that crashes the minecraft server Library. If someone exactly know, write down xD. Here my Systemd
