exception in thread thread-1, zmqerror: socket operation on non-socket.

any ideas on what's causing or how fix it?

import communication import gamestate import json import threading import time  def movement_strategy(comm):      def get_gamestate():         [token, msg] = comm.pub_socket.recv_multipart()         msg = json.loads(msg)         if msg["comm_type"] == "gamestate":             game_info = gamestate.gamestate( msg["comm_type"],                                              msg["timestamp"],                                              msg["timeremaining"],                                              msg["map"],                                              msg["players"]                                              )             print game_info.timeremaining             print game_info.timestamp         time.sleep(1)       thread = threading.thread(target=get_gamestate, args())     thread.start()
