发生了一件非常奇怪的事情，
我有一个用 MVC 3 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
，我决定做一些小改动，它似乎正在工作，但是以随机间隔保持故障
这是

随机间隔后发生的情况 我在收到此错误ErrorCode<ERRCA0017>:SubStatus<ES0006>
2-3 分钟后收到此错误 站点似乎工作正常

我没有更改与缓存
此错误相关的站点的先前版本的任何内容nt 发生在我在代码中测试它staging或在local environment
我以编程方式访问此缓存的任何位置时
我已经从 azure 门户复制粘贴了整个配置，我知道它是正确的，因为这些配置设置与
我刚刚使用之前工作的配置设置相同，Azure AppFabric Caching因为我需要保存sessions一些位置。所以唯一提到它的地方是在我的网站上web config，正如我所说的那样，所有配置都可以假设是正确的。

如果这可以有所帮助，这是堆栈跟踪

更新：-
突然我发现了一个新错误，在我看来这是许多网站谈论
错误描述的内部错误之一

一年多前有一篇关于此错误的有趣博客文章：Azure AppFabric Caching - ErrorCode:SubStatus : What to do？.

在初始化 DataCacheFactory 之前，将您正在使用的 dataCacheFactoryConfiguration 实例的 DataCacheFactoryConfiguration.ChannelOpenTimeout 修改为 2 分钟的较大值。（不能使用配置来设置值，因为在允许的限制内 20 秒）。此外，此建议仅用于调试目的，理想情况下在生产环境中不需要。这使底层能够以发生的实际错误进行响应。现在，如果您检查内部异常，您应该会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：如果这是由瞬态故障引起的，您应该考虑使用瞬态故障处理应用程序块（也支持 AppFabric 缓存）来实施重试策略。
