我在使用Windows Azure緩存與模擬器(即在本地而非雲上)時遇到問題。調試時的Windows Azure緩存 - 請求超時

我的系統配置是:

  • 的Windows 8
  • 的Visual Studio 2012更新1
  • Azure的SDK和模擬器1.8
  • 的Windows Azure緩存1.8.1
  • 的Web API
  • .NET 4.5

問題是:我們的服務器利用(在角色中)用於會話管理的Windows Azure緩存等。一旦服務器獲取來自客戶端的請求,它就開始與Windows Azure緩存進行通信,以便放置/獲取一些對象(例如會話對象) 。然後發生「超時」異常(Microsoft.ApplicationServer.Caching.DataCacheException)並且服務器無響應,在Visual Studio的輸出日誌中顯示以下消息。

...

當這種情況發生時,服務器剛剛關閉(即正在運行,但沒有響應)。

任何想法爲什麼發生這種情況?它與Windows 8有關嗎?

感謝,

我也有這個問題,追查下來的Hyper-V虛擬以太網適配器一臺機器上。禁用我安裝的兩個適配器修復了Azure緩存中的超時錯誤。在這臺機器上,我可以繼續保持連接到網絡/互聯網。

在另一臺機器上沒有安裝Hyper-V,並且禁用以太網適配器(斷開與互聯網的連接)「修復」了問題。所以要運行我的應用程序,我必須首先每次斷開與網絡的連接。

在這兩臺機器上,對緩存服務器(例如127.255.0.0,127.255.0.1,127.255.0.2等)進行IP查找時,Azure緩存開發似乎遇到問題,它適用於幾個請求,然後開始超時。從網絡斷開時,它始終有效。

在開始發生問題之前的幾個月,這對我而言在Windows 8機器上工作得很好。

更新

沖洗固定這對我來說DNS緩存,現在它的工作原理,同時連接到網絡。 ipconfig /flushdns

感謝您分享您的經驗! :) – soleiljy 2013-10-02 23:05:16

我還沒有能夠完全確認這一點,但這個問題似乎與在azure緩存dll中的遺留協議有關。

我能夠在我的默認緩存運行此配置來解決這個問題:

<dataCacheClient name="default" isCompressionEnabled="false" maxConnectionsToServer="4" useLegacyProtocol="false" > 

希望這有助於
