Azure AppFabric緩存。錯誤代碼<ERRCA0017>：子狀態<ES0006>

Question

有事情
我在MVC 3做了一個網站，部署在Azure中WebRole
它運行良好，最初在VS2010
作出 現在我用VS2012
一個很奇怪的事情 我決定做一些細微的變化，它似乎是工作，但不斷打破在隨機時間間隔
這是發生了什麼事隨機間隔我得到這個錯誤ErrorCode<ERRCA0017>:SubStatus<ES0006>
2-3分鐘得到這個犯錯後後

或網站似乎是工作的罰款

我還沒有從以前的版本與緩存
網站的改變任何東西這個錯誤不會NT發生時，我在staging或local environment
測試沒有地方在我的代碼即時訪問該緩存編程
我有複製粘貼整個配置，因爲它是從蔚藍的門戶網站，我知道它，它正確的，因爲這些是被前
工作相同的配置設置我只是用Azure AppFabric Caching，因爲我需要保存sessions一些地方。所以它提到的唯一的地方是在我的網站web config，正如我已經告訴所有的配置可以被認爲是正確的。

這是堆棧跟蹤，如果這能有一定的幫助

更新： -
突然我發現這似乎是我一個新的錯誤作爲內部錯誤很多網站談論
之一錯誤描述

有關於這個錯誤在一年前一個有趣的博客文章：Azure AppFabric Caching - ErrorCode:SubStatus : What to do?。

intializing的DataCacheFactory修改 dataCacheFactoryConfiguration實例的 DataCacheFactoryConfiguration.ChannelOpenTimeout您正在使用到2分鐘的大 值之前。 （不能使用配置來設置值，因爲 在允許的限制內20秒）。此外，此建議僅用於調試目的，並且理想情況下不應在生產 環境中需要 。這使底層可以迴應發生的實際錯誤 。現在，如果您檢查內部異常，您應該看到 導致請求失敗的原因。

請按照以下步驟找到內部異常，這將解釋爲什麼請求失敗。

注：如果這是由瞬時故障引起的，你應該考慮，以實現重試政策使用Transient Fault Handling Application Block（這也支持的AppFabric緩存）。
