Question

我正在遵循此实现来接收来自服务总线的消息：http://msdn.microsoft.com/en-us/library/windowsazure/hh851744.aspx。

问题在于，有时我会收到此错误，而我无法弄清楚我能做些什么来解决这个问题。

Answer 1

该错误很可能代表连接的某个段中的超时。这可能是您的客户端，天蓝色负载平衡器或实际托管消息队列的服务总线机器。

对于这种瞬态错误，建议添加重试机制。 This blog post对此有很好的指导。

Answer 2

我同意实施重试策略 - 应该解决大多数瞬态错误。以下是微软关于该主题的非常好的文章：

Retry guidance for specific services

Service Bus messaging exceptions

服务总线 - “服务器没有提供有意义的回复;这可能是由于过早的会话关闭引起的”
