910931 - Stackato gives 500 for requests that are made in short intervals randomly.

Status: VERIFIED FIXED

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:26.0) Gecko/20100101 Firefox/26.0 (Beta/Release)
Build ID: 20130829030201

Steps to reproduce:

I have an app deployed on stackato, osumo.paas.allizom.org. It uses appcache, which means that a lot of files will load initially when the browser grabs all the files to cache locally. However, some of the requests will fail with a 500 and the error {"code":"ECONNREFUSED","errno":"ECONNREFUSED","syscall":"connect"} 

The backend server is gunicorn with 4 gevent workers. I tried multiple instances as well without success.

I checked and my backend is never getting the requests (but connection refused?)

this appears to have started when i enabled `router2g` through stackato to support websockets for bug 907407. i have reverted to the default `router` to see if this resolves your issue. if it does, i plan on sticking with the default router until we can update to stackato 2.10. 

please give this some more testing and let me know how you make out.

Looks like that fixed it. I can test a little more to confirm, but i'm fairly certain this works.
