I tried traditional ways and answers to analyze my .DMP files. WinDbg doesn`t take it, it outputs:
Could not find the C:\program files\softwaredir\dumps\dumpname_0313.rsa.dmp
File, Win32 error 0n87
It's an Multi Theft Auto: San Andreas crash dump. .rsa.dmp
Why doesn`t WinDbg take it, does it have to do with a certain dump type?
If anyone would want to try opening, here is the dumpfile with the issue
I would like to know if you have the solution to solve the opening problem/or any other tool to open the dump.
But I really need the exception that caused the crash, so either I'll need advise on how to open it or if I can fix it.
For case 2 (can't solve it for me here) the crash memory locations are:
Version 1.3.5-release 6078.0.000

CS 0023 DS 002B SS 002B ES 002B FS 0053 GS 002B
This is what I did to generate and analyze a dump file:
Downloaded ProcDump (a free Sysinternals tool)
Created a folder c:\dumps
Added ProcDump to PATH
Entered procdump -ma -i c:\dumps into command prompt to start the JustInTime debugger
Opened the dump file in visual studio
Using this method we were able to resolve a difficult bug and determine what exception was causing my machine to crash.

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)
ExceptionFlags: 00000000
NumberParameters: 0
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.
Today I wanted to write a crash dump and I got the error message
0:000> .dump /ma c:\classid_loads_net4.dmp
Creating c:\classid_loads_net4.dmp - mini user dump
GenInvokeEnumStackProviders(C:\Windows\Microsoft.NET\Framework\v2.0.50727\mscordacwks.dll) failed, 0x8007007f
Dump successfully written
I googled for GenInvokeEnumStackProviders but there are no results at all.
What could the reason for this error message be and what impact could this have on the dump (which was successful according the last message)?
Using WinDbg 6.3.9600
Update 2014-09-18
Same error again today, reproducible at the moment. In Process Monitor I can see that WinDbg tries to access verifier.dll while writing the dump
C:\Program Files (x86)\Windows Kits\8.1\Debuggers\x86\verifier.dll
However, the file does not exist in that place. From the list of loaded modules I see it is loaded from
0:008> lm fm verifier
start end module name
6ddf0000 6de50000 verifier C:\Windows\syswow64\verifier.dll
In addition (not sure it is related) I get errors dumping the .NET heap:
0:008> !dumpheap -stat
c0000005 Exception in C:\Windows\Microsoft.NET\Framework\v2.0.50727\sos.dumpheap debugger extension.
PC: 6b55dbe8 VA: 00000000 R/W: 0 Parameter: 00000000
Still using WinDbg 6.3.9600
The problem persists, even after a reboot and after disabling application verifier.
I'm attempting to debug a manual dump file of a 64bit w3wp process with 64bit Windbg (Version 6.10). The dump was taken with taskmgr. I can't get anything from the !clrstack command. Here is what I'm getting:
!loadby sos clr
!runaway
User Mode Time
Thread Time
17:cf4 0 days 5:37:42.455
~17s
ntdll!ZwDelayExecution+0xa:
00000000`776208fa c3 ret
!clrstack
GetFrameContext failed: 1
What is GetFrameContext failed: 1?
Use !dumpstack command instead of !clrstack. It usually works.
Try getting the "native" call stack by doing "k" and see what that gets you. Sometimes, the stack isn't quite right and the !ClrStack extension is pretty sensitive.
I am trying to make a call to a method of a Windows COM interface from the Go language. I suspect I am doing something wrong in the way I invoke the call and would like to see how the registers change during the invocation.
But I have a hard time getting to it since I can't seem to set a breakpoint in WinDBG. The command "bu 64b6ea43" ends up not working with an error "Only part of a ReadProcessMemory or WriteProcessMemory request was completed". The full message is below.

To me it was problem because of ASLR.
running editbin /DYNAMICBASE:NO NameOfDetectedExe.exe fixed it.
Switched to Ollydbg which works. Learned that WinDbg sucks badly.
When i debug a programmer, I found too many lines useless info which appear in GDB. this kind of infomation may come from iphone framework. it is not logged by my code. the info like this
Node 48 TrialMT(102,102,101,101)
Node 58 TrialMT(102,102,101,101)
Node 69 TrialMT(102,102,101,101)
Node 72 TrialMT(102,102,101,101)
Just too much. so i can not find my log.
I want to known is there a way i can export GDB log to a file, so i can find my log info in the file later on.
thanks
In Xcode you can type GDB commands in the debugger console. There you can reset the stdout and stderr file descriptors to your preferred log file like this
(gdb) call (void)close(1)
(gdb) call (void)close(2)
(gdb) call (int)open("/tmp/out.log", 0x201, 0644)
$1 = 1
(gdb) call (int)dup(1)
$2 = 2
(gdb) continue
