which worker? Did you tried the latest master?

I have this in mi Procfile:

web: gunicorn -k eventlet main:app

and the eventlet is working fine with the patch, if I write -w 1 in that line, the server goes down.
Only see the issue when the server socketio is working with the java socketio web client.

Thanks for answer.
