How exit socket properly with Nodejs net

I have a problem in attempting to kill all processes inside a socket function in nodejs net: loops keep running after the socket disconnects. Is there a way to kill all processes called by the socket?

net.createServer(function (socket) {

  socket.on('end', function () {
    //How kill all processes of the current socket ???
  });
  socket.on('error', function () {
    //How kill all processes of the current socket ???
  });

  i=0;
  setInterval(function () {//Waiting other peer for 5sec
    i++;
    console.log("loop");
    if(i>=10){
      clearInterval(this);
    }
  }, 1000);

}).listen(1000);
