问题
I have a 32-bit application (targeting .NET 3.5) hosted on a 64-bit machine. I want to analyze the memory dump of this 32-bit application. I captured the memory dump using 32-bit adplus and cdb. I am loading the memory dump into 32-bit windbg. When I load .net 2.0 sos.dll and .net 2.0 mscorwks.dll into windbg and execute !clrstack, I get the following error: "Failed to find runtime DLL (mscorwks.dll), 0x80004005 Extension commands need mscorwks.dll in order to have something to do." What am I doing wrong?
Info as requested in the comments
ADPlus command line:
adplus -hang -quiet -p 2440 -o C:\temp
WinDbg commands:
0:000> .load <fullpathto>\sos.dll
0:000> lmvm mscorwks
start end module name
0:000> .exr -1
ExceptionAddress: 00000000
ExceptionCode: 80000007 (Wake debugger)

The dump indicates that no .NET 2 was loaded. Otherwise the output of lmvm mscorwks
should show the details of the .NET runtime, like this:
0:003> lmvm mscorwks
start end module name
61bc0000 6216e000 mscorwks (deferred)
Image path: C:\Windows\Microsoft.NET\Framework\v2.0.50727\mscorwks.dll
...
File version: 2.0.50727.5485
...
You mentioned that you loaded SOS by full path. If the dump was taken on your machine, you would typically load it using
0:003> .loadby sos mscorwks
In your case, this should already give you the hint that .NET was not loaded:
Unable to find module 'mscorwks'
If you're not so sure about the .NET version, try
.loadby sos clr; *** .NET 4
.loadby sos coreclr; *** Silverlight / Universal Apps
Maybe you had a typo in your AdPlus command line and specified the wrong process ID. If that PID accidentally exists, you got a wrong dump. Use |
to check the process name
0:003> |
. 0 id: 1e78 attach name: E:\...\NET2x32.exe
BTW: The -quiet
parameter of ADPlus is obsolete, you can omit it.
