RabbitMQ 和 SharedQueue 关闭

Question

我使用 RabbitMQ 发送简单的短整数信息，首先我将 id 发送到这样的一个项目：

    private void SendPgcIdToRabbitMQ(string id) 
    {
        var factory = new ConnectionFactory() { HostName = "localhost" };
        using (var connection = factory.CreateConnection()) 
        {
            using (var channel = connection.CreateModel()) 
            {
                bool durable = true;
                channel.QueueDeclare("XQueue", durable, false, false, null);

                var body = Encoding.UTF8.GetBytes(id);

                channel.BasicPublish("", "XQueue", null, body);
                Console.WriteLine(" [x] Sent {0}", id);
            }
        }
    }

和它的听众：

    public void Listener() 
    {
        var factory = new ConnectionFactory() { HostName = "localhost" };
        using (var connection = factory.CreateConnection()) 
        {
            using (var channel = connection.CreateModel()) 
            {
                channel.QueueDeclare("XQueue", true, false, false, null);

                var consumer = new QueueingBasicConsumer(channel);
                channel.BasicConsume("XQueue", false, consumer);

                Console.WriteLine(" [*] Waiting for messages. " +
                                  "To exit press CTRL+C");
                while (true) {
                    var ea =
                        (BasicDeliverEventArgs)consumer.Queue.Dequeue();

                    var body = ea.Body;
                    var message = Encoding.UTF8.GetString(body);
                    Console.WriteLine(" [x] Received {0}", message);

                    AddPGCFileID(message);

                    channel.BasicAck(ea.DeliveryTag, false);

                    Thread.Sleep(500);
                }
            }
        }
    }

它工作正常，所以在收到消息后我正在处理一些操作，然后我得到第二个 ID 并创建其他队列来做同样的事情：

        private void SendSurveyIdToRabbitMQ(int yID) 
    {
        var factory = new ConnectionFactory() { HostName = "localhost" };
        using (var connection = factory.CreateConnection()) {
            using (var channel = connection.CreateModel()) {
                bool durable = true;
                channel.QueueDeclare("YQueue", durable, false, false, null);

                var body = Encoding.UTF8.GetBytes(yID.ToString());

                channel.BasicPublish("", "YQueue", null, body);
                Console.WriteLine(" [x] Sent {0}", yID);
            }
        }
    }

并接收：

        public void InquiryListener() 
    {
        var factory = new ConnectionFactory() { HostName = "localhost" };
        using (var connection = factory.CreateConnection()) {
            using (var channel = connection.CreateModel()) {
                channel.QueueDeclare("YQueue", true, false, false, null);

                var consumer = new QueueingBasicConsumer(channel);
                channel.BasicConsume("YQueue", false, consumer);

                Console.WriteLine(" [*] Waiting for messages. " +
                                  "To exit press CTRL+C");
                while (true) {
                    var ea =
                        (BasicDeliverEventArgs)consumer.Queue.Dequeue();

                    var body = ea.Body;
                    var message = Encoding.UTF8.GetString(body);
                    Console.WriteLine(" [x] Received {0}", message);

                    StartProcessing(Convert.ToInt32(message));

                    channel.BasicAck(ea.DeliveryTag, false);

                    Thread.Sleep(500);
                }
            }
        }
    }

第一个队列发送和接收工作正常，但第二个我得到：

这很奇怪，因为它一直以这种方式工作，从一段时间以来我遇到了这个问题。我正在重置rabbitmq，删除所有队列等。找不到问题所在。有什么想法吗？

编辑： 我正在调试以了解第二个进程是否正确结束（第二个进程上的 eariel 崩溃不会导致 rabbitmq 出现问题）并且它通过了，我已经定价，因为 YQueue 上没有发生错误，但是在我的进程工作大约一分钟后（只等待，非传入消息，非处理）我在 XQueue 上遇到同样的异常

在执行while(true){ ... }之前先检查队列是否为空。
