title: Reason for zmq error code 156384763
body: <p>I am using zmq req/rep pattern communication. The implementation is pretty simple, the req sends some data and waits on recv. The rep receives the data, process and reply back.</p>
  
  <pre><code>//REQ
  zmq_connect
  zmq_send
  zmq_recv //blocking
  zmq_close
  
  //REP
  zmq_bind
  while(true) {
    while(data_received) {
      //miscellaneous process
      zmq_recv //non-blocking
        Print zmq_error_no if zmq_recv fails
    }
    zmq_send
  }
  </code></pre>
  
  <p>In the REP side, during zmq_recv timeout zmq_error_no 11 will be printed. But sometimes i am getting error no 156384763. could anyone tell the meaning for that error?</p>
