python - Rabbitmq错误: [Errno 10054] An existing connection was forcibly closed by the remote host

Question

我在 Python 中使用 Kombu 来使用持久的 RabbitMQ 队列。

Windows 中只有一个消费者在消费队列。此消费者产生以下错误:

Traceback (most recent call last):
  File ".\consumer_windows.py", line 66, in <module>
    message.ack()
  File "C:\Users\Administrator\Anaconda2\lib\site-packages\kombu\message.py", line 88, in ack
    self.channel.basic_ack(self.delivery_tag)
  File "C:\Users\Administrator\Anaconda2\lib\site-packages\amqp\channel.py", line 1584, in basic_ack
    self._send_method((60, 80), args)
  File "C:\Users\Administrator\Anaconda2\lib\site-packages\amqp\abstract_channel.py", line 56, in _send_method
    self.channel_id, method_sig, args, content,
  File "C:\Users\Administrator\Anaconda2\lib\site-packages\amqp\method_framing.py", line 221, in write_method
    write_frame(1, channel, payload)
  File "C:\Users\Administrator\Anaconda2\lib\site-packages\amqp\transport.py", line 182, in write_frame
    frame_type, channel, size, payload, 0xce,
  File "C:\Users\Administrator\Anaconda2\lib\socket.py", line 228, in meth
    return getattr(self._sock,name)(*args)
error: [Errno 10054] An existing connection was forcibly closed by the remote host

任一时刻队列中最多有 500 条消息。每条消息都很小，但它是一项任务，最多需要 10 分钟才能完成(尽管每条消息通常需要不到 5 分钟)。

我已尝试重新启动消费者、RabbitMQ 服务器并删除队列，但错误仍然存​​在。

我看过 this question然而the answer来自 2010 年，我的 rabbitmq.log 有不同的条目:

=ERROR REPORT==== 24-Apr-2016::08:26:20 ===
closing AMQP connection <0.6716.384> (192.168.X.X:59602 -> 192.168.Y.X:5672):
{writer,send_failed,{error,timeout}}

rabbitmq-sasl.log 中没有最近的事件。

为什么会发生此错误以及如何防止它发生？

我还在寻找答案。与此同时，我重新启动与我的兔子服务器的连接:

while True:
    try:
​
        connection = pika.BlockingConnection(params)
        channel = connection.channel() # start a channel
        channel.queue_declare(queue=amqp_q, durable=True) # Declare a queue
        ...
​
    except pika.exceptions.ConnectionClosed:
        print('connection closed... and restarted')
