今天上午，我們做了部署，以及四臺服務器一個反應遲鈍，與此異常：

任何想法會導致這種情況？它在重新啓動的時候修復了，我們之前沒有看到它。

Answer 1

這聽起來像你可能有另一個網站鎖定telerik DLL或現有的網站沒有釋放在部署過程中的文件上一個鎖。

我想：

1. 回收應用程序池，如果仍沒有響應，那麼：
2. 重啓的具體網站，如果仍沒有響應，那麼：
3. 重新啓動IIS，所有託管的網站。

如果最後一個選項不可行，我會重新啓動所有其他可能使用Telerik.web.ui dll的網站（通常位於這裏的子文件夾中：C：\ Program Files \ Telerik [Radcontrols或sitefinity相關的子文件夾]）。

我在使用MSBuild & Webdeploy部署站點時偶爾也會看到這個錯誤。通常第二次重新部署該網站會修復該網站。
