title: Celery Queue Hanging
body: <p>I've got one specific job that seems to hang my celery workers every so often. I'm using rabbitmq as a broker. I've tried a couple things to fix this, to no avail:</p>
  
  <ul>
  <li>Autoscaling the workers to allow the hung ones plenty of time to finish execution</li>
  <li>Setting a global timeout</li>
  </ul>
  
  <p>So I've come up a little short on what's causing this problem, and how I can fix it. Can anyone give me any pointers? The task in question is simply inserting a record into the database (MongoDB in this case.)</p>
  
  <p>Update: I've added <a href="http://celery.readthedocs.org/en/latest/configuration.html#std%3asetting-CELERYD_FORCE_EXECV" rel="nofollow">CELERYD_FORCE_EXECV</a>. We'll see if that fixes it.
  Update 2: nope!</p>
