When a WebSocketShard doesn't receive a heartbeat in time it tries to close the Websocket. If the close event of the socket doesn't emit in time either it assumes a zombie connection and emits its own close event, but the old connection still has the onClose and other event listeners attached. So if the old Websocket finally emits the close event the WebSocketShard receives that event and assumes it's from the new (re-)connection and closes again.
