发生了一件非常奇怪的事情，
我有一个在 MVC 3 中制作的网站，部署在 Azure WebRole 中，它
运行良好，最初是在 VS2010 中制作的，
现在我使用 VS2012 我
决定进行一些小的更改，它似乎正在工作，但以随机间隔不断分解这是
随机间隔后发生的事情，我在
2-3 分钟后ErrorCode<ERRCA0017>:SubStatus<ES0006>收到此错误此错误 网站似乎工作正常
我没有更改与缓存相关的站点的先前版本的任何内容
当我在staging或local environment中测试它时，此错误不会发生
在我的代码中没有任何地方 我以编程方式访问此缓存
我已经复制粘贴了整个配置，因为它是从 Azure 门户，我知道它是正确的，因为这些是相同的配置设置在
我只使用Azure AppFabric Caching之前工作，因为我需要sessions保存在某个地方。 因此，唯一被提及的地方是在我的网站中web config并且正如我所说，可以假定所有配置都是正确的。
这是堆栈跟踪，如果这可以有所帮助

突然我发现了一个新错误，在我看来，这是许多网站谈论

一年多前有一篇关于此错误的有趣博客文章：Azure AppFabric Caching - 错误代码：子状态：该怎么办？。
在初始化数据缓存工厂之前，修改 DataCacheFactoryConfiguration.ChannelOpenTimeout of the 您正在用于更大 值为 2 分钟。(无法使用配置来设置值，因为 允许限制为 20 秒)。此外，此建议仅是 用于调试目的，理想情况下不应在生产中需要 环境。这允许底层响应实际错误 发生了。现在，如果您检查内部异常，您应该看到 导致请求失败的原因。
请按照以下步骤查找内部异常，该异常将解释请求失败的原因。
注意：如果这是由暂时性故障引起的，则应考虑使用暂时性故障处理应用程序块(也支持 AppFabric 缓存)来实施重试策略。
