我的一些应用程序出了问题.它是在Windows 2003 Server(x86)中的IIS6下运行的基于wcf的应用程序:
在事件日志中,我从"W3SVC-WP"源(EventID = 2262)得到这样的错误:
ISAPI 'C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll' reported itself as unhealthy for the following reason: 'Deadlock detected'.
我正在尝试弄清楚发生了什么.我已按照此KB中的描述为Orphan Worker Process设置了转储.发生死锁时会创建一个小型转储.
然后我拿这个小型泵试图了解发生了什么.这是我被困住了.
我运行WinDbg x86,打开我的转储然后:
0:037> .loadby sos clr

0:037> !clrstack
The version of SOS does not match the version of CLR you are debugging. Please load the matching version of SOS for the version of CLR you are debugging.
CLR Version: 4.0.30319.1
SOS Version: …我试图找到我的转储文件中的CLR异常的底部,但我在尝试执行时遇到问题:
0:000> .loadby sos clr
The call to LoadLibrary(C:\ProgramData\dbg\sym\clr.dll\5348A1EF9a0000\sos) failed, Win32 error 0n126

我试着看看加载了什么,我看到了:

当我在我的解决方案中运行所有测试(大约800个测试)时,一段时间后会显示一个错误的弹出窗口,表明vstest.executionengine.x86.exe已停止工作.
