Running multiple insatnce of daphne? about daphne HOT 4 CLOSED

Daphne is asynchronous code, it doesn't need worker threads like gunicorn. If you want multiple processes (you should have maximum 1 per physical core on the machine), then run them as separate instances and use nginx/haproxy/or similar to loadbalance across them.

@andrewgodwin so to clarify, if one has 5 nodes, it's recommended to setup a single daphne process on each machine and then use an application load balancer across them?

@adihat Typically you'll want to run multiple processes on each instance. (One-per-core will generally work well.) And yes, then use load balancers to distribute between the multiple processes and multiple instances.

@andrewgodwin I am using nginx to load balance between 2 daphne processes and I see sometimes these kind of messages -
[daphne.http_protocol:365] Message on unknown channel u'daphne.response.PBWpKJGGxs!dJnxtfaczV' - discarding
I thought it because a websocket client that has a response channel on one daphne is balanced to the other. Is it possible? and if so, how can I work with more than one daphne on a specific machine with nginx?
Thank you
