title: Supervisord (exit status 2; not expected) ubuntu
body: <p>I'm trying to run Celery with Supervisord on Ubuntu, but am getting:</p>
  
  <pre><code>INFO exited: celery (exit status 2; not expected)
  INFO spawned: 'celery' with pid 15517
  INFO gave up: celery entered FATAL state, too many start retries too 
  quickly
  </code></pre>
  
  <p>This is the Supervisord script:</p>
  
  <pre><code>cd into the directory and activate the virtual environment 
  celery -A [APP_NAME].celery worker -E -l info --concurrency=2
  </code></pre>
  
  <p>If I run this script manually, Celery starts up without any issues. But running <code>sudo supervisorctl start celery</code> errors out with the error messages above. </p>
