Windbg和堆栈溢出异常 - 得到崩溃转储但Windbg输出无意义

Question

我想在活动ASP.NET 4.0网站上找到间歇性堆栈溢出异常的来源。我使用ADPlus（adplus_old.vbs，不是新的adplus.exe）捕获了一些崩溃转储，使用忽略所有其他类型异常的自定义配置（请参阅第1个答案：Help catching StackOverflowException with WinDbg and ADPlus）。

我在运行应用程序的服务器上运行Windbg。该服务器是基于Intel的运行64位Win 2003.WinDbg版本是64位的6.12。我生成的组件的PDB文件，我怀疑异常来自并将它们放在网站的/ bin文件夹中（有几个程序集，我没有PDB文件，但我认为他们不牵连在这个问题）。我将环境变量_NT_SYMBOL_PATH指向/ bin文件夹。 WinDbg显示符号路径为：C：\ WINDOWS \ Microsoft.NET \ Framework64 \ v4.0.30319; D：\ InetPub \ LiveSites \ MySite \ bin

当我运行WinDbg时，打开崩溃转储后运行.loadby sos clr then！clrstack。输出非常小 - 当我在测试站点上设置了一个故意的S/O时，我清楚地指出了导致异常的方法。出了什么问题？

运行可提供有关异常的详细信息 “分析-v！”。
