I see following call stack for finalizer thread. Is it normal to have a call to WaitForSingleObject at top in finalizer? Is there anyway I can determine if its not deadlocked or waiting for really long time? 0:009> k Child-SP RetAddr Call Site 000000
I am trying to understand how !address -summary report managed allocations. I have following code to try to test it out. I basically change the size of array and then attach windbg to inspect results for !address -summary static void Main(string[] ar

I have a dump which has both .NET versions loaded: 0:000> lm m clr start end module name 65490000 65aff000 clr (deferred) 0:000> lm m mscorwks start end module name 6a980000 6af2c000 mscorwks (deferred) Now I'm uncertain which version of SOS to use.
I've started to read some materials on advanced debugging tools and techniques. I use VS2012 Ultimate and the target framework is .NET 4.0. I got to the point where I need to load SOS.dll in the Immediate window during a debug session and it just doe
I've set up ADPlus / cdb as the default Just-In-Time debugger on my machine. When any process has an unhandled exception or crashes for any other reason, I want ADPlus to generate a crash dump for me. I'm using an ADPlus config file to set the output
How can I print the string value of all the System.String objects on the current thread's clrstack? Pseudo code for what I want to do: foreach ($string in !dso -type System.String) !do $string or better yet foreach ($string in !dso -type System.Strin
Let's say I have a memory dump of a process. I want to run a report on it, so essentially I want to open WinDBG, load SOS and run a script that runs some commands, parses the output and then runs some more commands based on that. Apart from hackish s

I am working on a mixed-mode app (C++/CLI, C++, some C#) and when it crashes in the field a memory dump gets created. I usually get these dumps from the customer and try to figure out what went wrong. The question is - how to handle post-mortem debug
I'm debugging a test that periodically raises an IOException, noting that a file can not be deleted because it is being used by another process. I suspect that the process is indeed my test harness, and that some other thread in the process hasn't di
I am debugging a hangdump coming from a production server using WinDbg with the SoS extension. There is a string parameter in one of the stacks, that I need to know the value of. However, it is a rather large string, and WinDbg won't print it when I
Background: I'm new to WinDbg and trying to get it running for the first time. I want to examine a memory dump I took from a running ASP.NET 4 site hosted in IIS 7 on Windows Server 2008 (x86) and downloaded to my local machine. I installed the debug

Title kinda says it all. The usual SOS command !bpmd doesn't do a lot of good without a name. Some ideas I had: dump every method, then use !bpmd -md when you find the corresponding MethodDesc not practical in real world usage, from what I can tell.
I am looking of a description of the output generated by the !SyncBlk command of SOS. Particularly I found no useful explanation on the column "MonitorHeld". This column shows high values in a series of crash dumps. Example: 0:000> !SyncBlk I
