title: Celery error "Received 0x00 while expecting 0xce"
body: <p>I try to use <strong>celery</strong>. I have installed <strong>rabbit-mq</strong> by command from celery tutorial:</p>
  
  <pre><code>sudo apt-get install rabbitmq-server
  </code></pre>
  
  <p>And all worked well while I write my code in one file and run it to test functionality. But when I tried to add my code in Django views, and then to do concurrent requests to my views, I got this kind of exception:</p>
  
  <pre><code>File "/home/kinmanz/PycharmProjects/GitFace/myvenv/lib/python3.5/site-packages/amqp/connection.py", line 464, in drain_events
      return self.blocking_read(timeout)
    File "/home/kinmanz/PycharmProjects/GitFace/myvenv/lib/python3.5/site-packages/amqp/connection.py", line 468, in blocking_read
      frame = self.transport.read_frame()
    File "/home/kinmanz/PycharmProjects/GitFace/myvenv/lib/python3.5/site-packages/amqp/transport.py", line 251, in read_frame
      'Received {0:#04x} while expecting 0xce'.format(ch))
  amqp.exceptions.UnexpectedFrame: Received 0x00 while expecting 0xce
  </code></pre>
  
  <p>I think that problem may be in concurrency of request, and I should somehow to make queue concurrent safe.</p>
  
  <p>I use Python 3.5, Celery 4.0.0, RabbitMQ 3.5.7</p>

  <p>Actually problem in <strong>amqplib</strong> see answer below.</p>
