title: redis is running but I'm getting "Error 111 connecting to localhost:6379. Connection refused"
body: <p>I 'm using django + redis +  celery. It works: tasks are queued and executed. But every now and then I get a bunch of errors saying </p>
  
  <blockquote>
    <p>Cannot connect to redis://localhost:6379//: Error 111 connecting to localhost:6379. Connection refused</p>
  </blockquote>
  
  <p>If I check the uptime of my <code>redis-server</code> process, I see it has been up from before the errors started, so it never crashed or anything.</p>
  
  <p>Any idea what's going on? what can I check to see what's happening?</p>
  
  <p>Thanks!</p>
