这发生在运行Windows 2008 R2 64位的服务器上。

导致此错误的原因是什么？如何防止它发生？

2 个答案:

答案 0 :(得分：6)

此问题的线索在“例外代码：

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

此异常代码表示CLR引发了“软堆栈溢出”。请参阅本MSDN Library文章末尾的评论：

  

StackOverflowException Class

您需要做的是安装Debug Diagnostic Toolkit并将其配置为在发生此崩溃时转储您的工作进程。

一旦捕获了进程转储，就需要将其加载到WinDBG中并使用SOS 缩小根本原因。

有几篇关于如何分析工作进程崩溃转储的精彩文章：

  

.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

Tess Ferrandez的文章很棒，我学会了从她的实验室掌握WinDBG和SOS。

答案 1 :(得分：2)

加入Kev的优秀答案 -

  1. 右键点击＆gt;我的电脑＆gt;属性＆gt;高级选项卡＆gt;单击“启动和恢复”下的“设置”按钮＆gt;选择“完全内存转储”并指定一个位置，其中有足够的硬盘空间等于服务器中的RAM量。

  2. 重新发生崩溃并且内存转储成功后。安装WinDBG，打开WinDBG，文件＆gt;打开＆gt;加载内存转储（.dmp）

  3. 然后加载SOS（例如.loadby sos mscorwks）

  4. ！clrstack

    5. 这将产生一个巨大的堆栈跟踪，很可能会识别一个递归函数或一些巨大的分配，正如Brian Grunkemeyer - MSFT在Kev提供的链接中所说的那样。

    您可能必须对递归调用的深度进行限制......或类似的东西。

    祝你好运！如果您需要诊断帮助，可以随时致电Microsoft PSS。在发出！analyze和！clrstack之前，请记得从Microsoft下载Public Symbols，以便查看方法名称。如果需要在转储文件中查看Microsoft DLL中的方法体，则需要私有符号（仅适用于Microsoft工程师）。
