I have a Django web application that uses Gunicorn and runs good locally, but when I deploy app on EC2, I see that Gunicorn is failing:

 $ gunicorn_django -b 127.0.0.1:8000 --settings=myapp.settings.dev --debug --log-level info
 2012-09-16 17:39:24 [28333] [INFO] Starting gunicorn 0.14.6

 2012-09-16 17:39:24 [28333] [INFO] Reason: Worker failed to boot.

I tried logging with --spew but it keeps on running and no error is shown.

How can I debug this issue?

python django gunicorn
