這個工作進程崩潰的原因是什麼？

Question

我們在ASP.NET 2.0應用程序中遇到了一個工作進程崩潰。

下面是當工作進程崩潰的轉儲報告：

發生這種情況，在運行Windows 2008 R2 64位我們的服務器上。

是什麼導致了這個錯誤，我該如何防止它發生？

Answer 1

的線索，這個問題是在異常代碼：

 
Sig[6].Name=Exception Code 
Sig[6].Value=e053534f  <====== this is the clue 

這個異常代碼表明有一個「軟堆棧溢出」由CLR提高。請參閱評論在這個MSDN庫文章的結尾：

StackOverflowException Class

什麼你需要做的是安裝Debug Diagnostic Toolkit，並配置它時，這個崩潰發生傾倒你的工作進程。

一旦捕獲了進程的轉儲，您需要將其加載到WinDBG中，並使用SOS 來縮小根本原因。

有關於如何分析一個工作進程崩潰轉儲幾個大文章：

.NET Debugging Demos - Information and setup instructions - Tess Ferrandez

Diagnosing Tricky ASP.Net Production Issues with DebugDiag and winDbg

System.StackOverflowException with IronPython 2.6.0 and 2.6.1

苔絲Ferrandez的文章是巨大的，我學會了從她的實驗室掌握WinDBG和SOS。

Answer 2

要添加到千電子伏的出色答卷 -

1. 右鍵單擊>我的電腦>屬性>高級選項卡>點擊設置按鈕開始下起來，恢復>選擇「完全內存轉儲」，並指定一個位置足夠的硬盤空間等於服務器中的RAM數量。

2. 一旦崩潰重新發生並且內存轉儲成功。安裝WinDBG中，開拓WinDBG中，文件>打開>加載內存轉儲（.dmp）提供

3. 然後加載SOS（如.loadby索斯mscorwks）

4. ！clrstack

這將微軟在Kev提供的鏈接中表示，Brian Grunkemeyer會推出一個巨大的堆棧跟蹤，最有可能確定一個遞歸函數或一些巨大的分配。你可能會不得不限制遞歸調用的深度...或類似的東西。

祝你好運！如果您需要診斷幫助，您可以隨時致電Microsoft PSS。請記住，在發佈！analyze和！clrstack之前，請先從Microsoft下載公共符號 - 以查看方法名稱。如果您需要在轉儲文件中查看Microsoft DLL中的方法體，則需要使用專用符號（僅適用於Microsoft工程師）。
