如果我等待一兩分鐘，該網站來很好。很明顯，這是一個首要問題。任何人有任何想法如何解決這個問題？

我的配置：

• MVC 4
• .NET 4.5
• RavenDB 2.0.2360

更新：的Azure團隊正在研究這個作爲Azure網站可能存在的缺陷。只要我聽到任何消息，就會有更新。

證實了這一點，如天青網站的錯誤，它現在已經推出出。我沒有任何額外的細節，但該網站現在可行（2013年8月30日），並且我沒有對代碼做任何結構性更改。

Answer 2

看看事件日誌，它會給你更多的信息。 它看起來像東西是防止日誌適當寫入，檢查權限，特別是，你可能有CREATE_FILE權限，但不能寫權限
