RabbitMQ报错 Already closed: The AMQP operation was interrupted

C#使用rabbitmq在接收消息事件处理中报错：

Already closed: The AMQP operation was interrupted: AMQP close-reason, initiated by Peer, code=505, text='UNEXPECTED_FRAME - expected content header for class 60, got non content header frame instead', classId=60, methodId=40

解决办法是将接收事件代码里面末尾加个线程休眠“System.Threading.Thread.Sleep(1);”

/// 

/// 监听消息队里的消息
/// 
/// 外围业务方法
public static void Receive(Func func)
{
    try
    {
        //如果未连接则重连连接队列
        AgainInitMessageQueue();

        //创建消费者对象
        var consumer = new EventingBasicConsumer(channel);
        //监听消费事件,如果执行shutdown了，此事件会执行失败
        consumer.Received += (model, ea) =>
        {
            //接收到的消息                    
            var message = Encoding.UTF8.GetString(ea.Body.Span);
            //委托外围方法处理业务
            var result = func(message);
            if (result)
            {
                //业务处理成功后单条通知生产者
                channel.BasicAck(ea.DeliveryTag, true);//手动应答MQ已经成功接收,批量应答
                LogHelper.Info(typeof(MessageQueueFactory), $"MessageQueueFactory.Receive()-消费成功，message={message}");
            }
            else
            {
                //业务处理失败需要重回队列等待消费
                //channel.BasicReject(ea.DeliveryTag, true);//拒绝接收单条消息，是否重回队列
                LogHelper.Error(typeof(MessageQueueFactory), $"MessageQueueFactory.Receive()-业务处理失败，进入缓存等待重新入列，message={message}", true);

                //###为了防止队里一直处于等到出列，导致后面数据无法消费，此处自动消费成功，进入缓存等待重新入列消费####
                //添加处理失败的数据进缓存中
                //添加消息重试次数缓存 超过上限不再进行重试
                var mqBaseModel = SerializerHelper.DeserializerJson(message);
                if (mqBaseModel != null)
                {
                    int retryTimes = ConvertBasic.ToInt32(RedisClient.GetValue(CacheKey.SendMsgFailRetryKey + mqBaseModel.MQCode));
                    RedisClient.SetValue(CacheKey.SendMsgFailRetryKey + mqBaseModel.MQCode, retryTimes + 1);
                }
                var ret = RedisClient.SAdd(CacheKey.SendMsgFailListKey, message);
                if (!ret)
                {
                    LogHelper.Error(typeof(MessageQueueFactory), $"MessageQueueFactory.Receive()-添加处理失败的数据进缓存中失败，message={message}", true);
                }
                channel.BasicAck(ea.DeliveryTag, true);//手动应答MQ已经成功接收,批量应答
            }
            Thread.Sleep(1);
            //此行代码必须，不然写入队列消息会报错
            //错误消息：Already closed: The AMQP operation was interrupted: AMQP close-reason, initiated by Peer, code=505, text='UNEXPECTED_FRAME - expected content header for class 60, got non content header frame instead', classId=60, methodId=40
        };
        //监听shutdown事件
