我有一个Django应用程序使用DjangoChannels，Djangochannelrestframework。它建立了一个与ReactJS前端的WebSocket连接。作为通道层，我使用Redis这样的

CHANNEL_LAYERS = {
    "default": {
        "BACKEND": "channels_redis.core.RedisChannelLayer",
        "CONFIG": {
            "hosts": [("redis", 6379)],
        },
    },
}

Redis和Django在docker中运行。我的redis docker设置是

redis:
    image: "redis:7.0.4-alpine"
    command: redis-server
    ports:
      - "6379:6379"
    networks:
      - nginx_network

当我在生产服务器上运行我的应用程序时，一切都工作了5-8个小时。但在这段时间之后，如果Django应用程序试图通过ws发送消息，如果福尔斯错误

我知道它与Redis复制有关，但不知道为什么一段时间后会福尔斯，以及如何修复它
