Question

我已经启动并运行了MQTT代理（Mosca）。

我正在使用paho-mqtt从Python连接到它。当我的客户端连接数大约为5-6时，一切都很好，只有几次客户端断开连接发生了，但是当客户端数量增加时，断开连接的频率也增加了。尤其是当客户端持续发布时，几次客户端在发布后都会断开连接。有人可以帮我解决这个问题吗？

请让我知道是否需要其他信息？

def on_connect(client, userdata, flags, rc):
    if rc==0:
        print("connected OK Returned code=",rc)
    else:
        print("Bad connection Returned code=",rc)

    print("Subscribing to topic","data/#")
    client.subscribe("data/#")


def on_disconnect(client, userdata, rc):
   print("Client Got Disconnected")
   if rc != 0:
       print('Unexpected MQTT disconnection. Will auto-reconnect')

   else:
       print('rc value:' + str(rc))

broker_address="ip"
port = 'port'
print("creating new instance")
client = mqtt.Client(clean_session=True) #create new instance
client.on_connect = on_connect
client.on_message = on_message #attach function to callback
client.on_disconnect = on_disconnect

print("connecting to broker")
client.connect(broker_address, port=port,) #connect to broker
client.loop_forever() #stop the loop

在MQTT代理中发布后，客户端断开连接
