我试图在实时 ASP.NET 4.0 站点上查找间歇性堆栈溢出异常的来源。我使用 ADPlus(adplus_old.vbs，而不是新的 adplus.exe)使用忽略所有其他类型异常的自定义配置捕获了一些故障转储(请参阅此处的第一个答案:Help catching StackOverflowException with WinDbg and ADPlus)。
我在运行应用程序的同一台服务器上运行 Windbg。服务器是基于英特尔的运行 64 位 Win 2003。WinDbg 版本是 64 位的 6.12。我为我怀疑异常来自的程序集生成了 PDB 文件，并将它们放在站点的/bin 文件夹中(有几个程序集我没有 PDB 文件，但我认为它们与此问题无关)。我将环境变量 _NT_SYMBOL_PATH 指向/bin 文件夹。 WinDbg 将符号路径显示为:C:\WINDOWS\Microsoft.NET\Framework64\v4.0.30319;D:\InetPub\LiveSites\MySite\bin
当我运行 WinDbg 时，在打开故障转储后，我运行 .loadby sos clr 然后运行 !clrstack。输出非常小——当我在测试站点上设置一个有意的 S/O 时，我清楚地知道导致异常的方法。出了什么问题？

最佳答案
运行“!analyze -v”可能会提供有关异常的更多信息。
关于asp.net - Windbg 和堆栈溢出异常 - 崩溃转储但 Windbg 输出毫无意义，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/9159038/
