Django channels not correctly handling WebSocket connections under high load
Could someone explain I'm working with an scenario with Django Channels while trying to handle multiple WebSocket connections under high load... I have configured Django Channels to work with Redis as the channel layer, but when I try to connect about 100 clients simultaneously, I'm seeing intermittent connection drops and receiving the following behavior in the logs: `ConnectionClosedError: 1006`. Here’s a simplified version of my configuration: ```python # settings.py CHANNEL_LAYERS = { 'default': { 'BACKEND': 'channels_redis.core.RedisChannelLayer', 'CONFIG': { "hosts": [ ("127.0.0.1", 6379), ], }, }, } ``` I'm using Django 4.0 and Channels 3.0. My consumer looks like this: ```python from channels.generic.websocket import AsyncWebsocketConsumer class ChatConsumer(AsyncWebsocketConsumer): async def connect(self): await self.accept() async def disconnect(self, close_code): pass async def receive(self, text_data): await self.send(text_data="Message received!") ``` To test this, I created a simple HTML page that connects to the WebSocket endpoint using JavaScript: ```javascript const socket = new WebSocket('ws://localhost:8000/ws/chat/'); socket.onopen = function() { console.log('WebSocket connected!'); }; socket.onclose = function(event) { console.log('WebSocket closed: ', event); }; for (let i = 0; i < 100; i++) { // simulate multiple connections socket.send('Hello!'); } ``` When I run this, I noticed that the connections drop after sending several messages, and the clients receive the `ConnectionClosedError`. I tried adjusting the `ASGI_APPLICATION` and increasing the Redis connection pool limit, but that didn't seem to help. Is there anything else I can do to ensure that my WebSocket connections remain stable under load? I'm coming from a different tech stack and learning Python. Is this even possible?
