間歇性裝配加載錯誤

Question

我們有一個利用插件的網絡應用程序。該系統用於許多成功部署的安裝，但在一個實例中，我們看到一個間歇性問題。偶爾它將無法加載用戶創建的插件 - 請參閱下面的融合日誌。當它失敗時，用戶將服務器切換到其冗餘服務器並繼續運行，直到問題出現在冗餘服務器上（沒有特定的時間間隔 - 可能是幾個小時到幾周），然後再切換回原始服務器（在那裏也可以）。我們已經提供了插件的來源，並確認它不是代碼/ dll本身的問題。

上什麼可能會導致它在間歇這樣失敗有什麼想法？

程序集加載時的簽名是什麼？你可以通過attachvto調試器和viwing加載的模塊來找到它。 與加載失敗時的字符串名稱不同嗎？

也使用fuslogview.exe作爲工具並記錄所有模塊加載失敗，當加載失敗時，fuslogview詳細信息將爲您提供組件加載失敗原因的詳細信息。
