title: Resque doesn't create new jobs
body: <p>I'm using Resque on heroku.
  After I enqueue a command on the console:</p>
  
  <pre><code>Resque.enqueue(UserBG, 35328)
  </code></pre>
  
  <p>I get this output:</p>
  
  <pre><code>=&gt; [:after_enqueue_scale_up]
  </code></pre>
  
  <p>And it looks like it didn't run the job.
  I've after_enqueue_scale_up is a method in the Heroku AutoScaler.</p>
  
  <p>What does it mean? And why isn't the job enqueued?</p>
  
  <p>Thanks</p>
