title: Heroku Error H13
body: <p>I've been getting this error now on &amp; off for the past couple days since I deployed my application to heroku. It happens both before I started using unicorn as a server as well as afterwards. I can sometimes get it back up and running by using <code>heroku run rake db:migrate</code> then <code>heroku restart</code> but this only fixes it for a couple hours and it's broken again. As for the webpage it's saying "Application error". The logs aren't very helpful but here's what it says each time this error happens:</p>
  
  <pre><code>[2014-10-27T21:13:31.675956 #2] ERROR -- : worker=1 PID:8 timeout (16s &gt; 15s), killing
  [2014-10-27T21:13:31.731646 #14]  INFO -- : worker=1 ready
  [2014-10-27T21:13:31.694690 #2] ERROR -- : reaped #&lt;Process::Status: pid 8 SIGKILL (signal 9)&gt; worker=1
  at=error code=H13 desc="Connection closed without response" method=GET
  </code></pre>
  
  <p>I'm just using the free version of heroku, I want to make sure it works before upgrading but is that my only option at this point?</p>
  
  <p>Also I am able to run this locally perfectly fine using either <code>rails server</code> or <code>foreman start</code>.</p>
