Hello! On the production service, we are using channels and channels Redis to deliver heavy updates on the web socket clients and it has worked fine for us for the last six months.
However, since the day that we switched to using the new PubSubChannelLayer, we are facing the problem of the constant infinite growth of memory consumption. and the only way around that we have found is restarting the server process on a constant interval to release the memory back.
Here you could find some metadata about the system that we are running:
Socket Updates are mostly generated by management commands which are running outside of the context of server processes and they call group_send to provide consumers with new updates.
channels==3.0.4
channels-redis==3.3.0
the server is running under an Nginx - uvicorn==0.12.1 stack with the supervisor as the process manager. however, we have tested gunicorn and daphne as well and the memory problem stayed the same.
OS: Ubuntu Server 18
