Windbg - The version of SOS does not match the version of CLR you are debugging.
.NET을 호스팅하고 있는 Windows Server 2008 R2의 w3wp.exe에 대해 덤프를 뜨고 예의 ".loadby sos clr" 명령어로 SOS 확장 DLL을 로드했습니다.
그리곤 clrstack 명령어를 실행하는데 다음과 같이 오류가 발생했습니다.
0:000> !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: 4.0.30319.296
SOS Version: 4.0.30319.18010
Failed to load data access DLL, 0x80004005
Verify that 1) you have a recent build of the debugger (6.2.14 or newer)
2) the file mscordacwks.dll that matches your version of clr.dll is
in the version directory or on the symbol path
3) or, if you are debugging a dump file, verify that the file
mscordacwks_<arch>_<arch>_<version>.dll is on your symbol path.
4) you are debugging on supported cross platform architecture as
the dump file. For example, an ARM dump file must be debugged
on an X86 or an ARM machine; an AMD64 dump file must be
debugged on an AMD64 machine.
You can also run the debugger command .cordll to control the debugger's
load of mscordacwks.dll. .cordll -ve -u -l will do a verbose reload.
If that succeeds, the SOS command should work on retry.
If you are debugging a minidump, you need to make sure that your executable
path is pointing to clr.dll as well.
덤프를 뜬 대상 컴퓨터에 설치된 CLR 버전이 windbg를 실행한 컴퓨터의 sos 버전보다 더 높았던 것입니다. 이 문제를 해결하려면 덤프를 생성했던 그 컴퓨터의 sos.dll 을 덤프를 분석하는 windbg가 실행되는 컴퓨터로 복사해 와야 합니다.
제 경우에는 .NET 4.0 64비트였기 때문에 대상 컴퓨터에서 "C:\Windows\Microsoft.NET\Framework64\v4.0.30319\sos.dll" 파일을 로컬의 c:\temp 폴더에 복사해 왔습니다.
자, 이제 잘못 로드된 sos.dll 을 windbg에서 언로드 시키고,
0:000> .unload
Unloading C:\Windows\Microsoft.NET\Framework64\v4.0.30319\sos extension DLL
.chain 명령어로 확인해 보면 sos.dll 이 없어진 것을 볼 수 있습니다.

지금부터는 ^^ 마음껏 sos 확장 명령어를 사용하시면 됩니다.
