Question

Flask service not responding after running for a few days

I have a Python Flask service running on my Ubuntu instance. I’m using WSGI and Apache to serve my application. Everything works well as soon as I launch the app and typically a few days afterwards. The problem is, after a few days, my service stops responding. When I ssh back into my instance, I can see python is still running, but the service no longer responds. Trying to curl to localhost results in Connection reset by peer timeout.

The service is still only being hit by a couple of developers, so I would be surprised if the problem is based on load. What can I do to try to diagnose this problem further?
