I am getting the Application Error page when I try and see my page on heroku. This behaviour is completely independent of me pushing any new code. Every now and then the website will simply crash. It usually comes back with a few reloads.

My procfile looks like this:

web: python manage.py run_gunicorn -b 0.0.0.0:\$PORT -w 9 -k gevent --max-requests 250 --preload --settings=myblog.production_settings

and the output of heroku logs is:

2013-08-27T21:58:35.847326+00:00 heroku[web.1]: Starting process with command `python manage.py run_gunicorn -b 0.0.0.0:\40311 -w 9 -k gevent --max-requests 250 --preload --settings=myblog.production_settings`

This does not seem to be related to a similar error which I posted about earlier Though I could post it there if people think its better.

I would heavily not recommend doing --max-requests 250 with gevent — that completely defeats the purpose of using it in the first place :)
