title: Can't start/stop openshift application
body: <p>I have an application on openshift which has suddenly stopped running.<br>
  The following cartridges are used :</p>
  
  <ul>
  <li>Mysql</li>
  <li>Cron</li>
  <li>Nodejs</li>
  </ul>
  
  <p>The only information about the crash of the app is the following from nodejs.log :  </p>
  
  <pre><code> DEBUG: Sending SIGTERM to child...
  </code></pre>
  
  <p>Now, when I try to rhc start / stop / restart the app, I got the following messages :</p>
  
  <pre><code>Failed to execute: 'control stop' for /var/lib/openshift/&lt;username&gt;/nodejs
  Failed to execute: 'control stop' for /var/lib/openshift/&lt;username&gt;/cron
  Failed to execute: 'control stop' for /var/lib/openshift/&lt;username&gt;/mysql
  </code></pre>
  
  <p>I can manually start the app by ssh in the app and executing </p>
  
  <pre><code>./mysql/bin/control start
  ./nodejs/bin/control start
  ./cron/bin/control start
  </code></pre>
  
  <p>Why can't the app be automatically restarted ? </p>
