RabbitMQ（aiopika）ConnectionResetError:[Errno 104]对等方重置连接

Question

我们有一个websocket服务器，它执行以下操作-

• 用例-流式音频数据通过Websocket从前端发送到此服务器
• Websocket服务器使用aio_pika从Python客户端连接到RabbitMQ并发布音频数据
• 为每个新的web套接字连接打开RabbitMQ连接

WEBSOCKET\u代码

@app.websocket('/ws')
async def websocket(websocket: WebSocket, meeting_id: str, user_id: str):
    global connections_ws, counter, audio
    conn_id = meeting_id
    print('before try')
    try:
        if not conn_id or conn_id == "-1":
            await websocket.close()
        print('before')
        await connections_ws.connect(websocket, conn_id)
        print('after')
        # hard coded user-id for now
        payload = {'user_id': user_id,
                   'meeting_id': meeting_id}

        print('http://{}/speechx'.format(API_URL_TRANS_SERVER))
        resp = requests.post('http://{}/speechx'.format(API_URL_TRANS_SERVER), json=payload)

        print("amqp://user:user123@{}/".format(RABBITMQ_URL))
        # Perform connection
        connection = await connect(
            "amqp://guest:guest@{}/".format(RABBITMQ_URL)
        )
        # Creating a channel
        channel = await connection.channel()
        exchange = await channel.declare_exchange("my_exchange", durable=True)

        while (True):
            receive_audio = await websocket.receive_bytes()

            # Sending the message
            await exchange.publish(
                Message(receive_audio),
                routing_key=meeting_id,
            )

    except Exception as err:
        await channel.close()
        await connection.close()
        connections_ws.disconnect(websocket, conn_id)
        print(f"Disconnect: {err}")

问题

问题是，如果我们有一个长时间运行的websocket或rabbitmq连接，以及其间来自不同客户机的3-4个其他短期连接，那么当我们等待连接时，有时候websocket服务器将无法接受到Rabbit MQ的新连接
