Beanstalk application randomly transitions from Ok to Severe

I've been finding that the last two nights my EB app has been falling on its face. I've been getting the error

Environment health has transitioned from Ok to Severe. None of the instances are sending data.

When this happens I receive an email alert from AWS saying that the server is down but I can't make any changes, request logs because I'm getting an error that the app is in an invalid state. I've been restarting my EC2 instance and that seems to have solved things but it could be a coincidence that it worked.

I'm not sure where to start with this but as a background I have a python/django application
