Hi! 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 Index SyncBlock MonitorHeld Recursion Owning Thread Info SyncBlock Owner ...
Hello, I have used the following sos command to enumerate all instances of a particular type in a running asp application (hosted on windows xp 4 GB machine). .foreach (obj { !dumpheap -type ::my type:: -short ::start of address space:: ::end of address space:: }) { !objsize ${obj} }. This enumerates all objects of the given type in ...
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. Even if I wrote a macro to limit the dump to anonymous types/methods, there's no ob...
I use SOS.dll in VisualStudio to debug my C# program. The program is as below. The debug command is !DumpStackObjects. class Program { static void Main() { Int32 result = f(1); } static Int32 f(Int32 i) { Int32 j = i + 1; return j; <===========BreakPoint is here } } After I...
I have an object, which I believe is held only by a WeakReference. I've traced its reference holders using SOS and SOSEX, and both confirm that this is the case (I'm not an SOS expert, so I could be wrong on this point). The standard explanation of WeakReferences is that the GC ignores them when doing its sweeps. Nonetheless, my object ...
I'm trying to automate the process of opening crash dumps for managed applications and retrieving the stack trace. Windgb works sometimes, but getting it to load the correct version of sos.dll is a nightmare unless the machine processing the dump is practically identical to the machine where the dump occured. Visual Studio, on the othe...
just downloaded SourceOffsite trial version and was impressed by the new winforms UI. i am curious which (third-party) components were used for ribbon/docking etc. If you know, info would be appreciated ;) ...
Hi, I know this was answered before, but I'd like to pose a somewhat different question. Is there any conceivable way to implement GC.GetAliveInstancesOf(), that can be evaluated in Visual Studio Debug Watch window? Sasha Goldstein shows one solution in this article, but it requires every class you want to query inherit from a specific...
I am able remote debug into a process that is running both native and managed code on a VM from my host machine. Also, on the VM I have been using the psscor2 extension with windbg to analyze the .net heaps. I find my self jumping back and forth between Visual Studio 2008 in my host and WinDbg in the VM while attempting to locate and f...
Is there any microsoft or even non-official documentation for SOS for Silverlight. Other than a few web posts I have seen zero documentation for it on MSDN. Even official documentation for the CLR version of SOS seems hard to find, this ancient article mentions a sos.htm file that is included in the windows SDK but it doesn't appear to...
Using sos, I can get the method table entry list for a particular class: !DumpMT -MD 1d3c58 PDB symbol for mscorwks.dll not loaded EEClass: 001d195c Module: 001d2f2c Name: Class1.B mdToken: 02000005 BaseSize: 0xc ComponentSize: 0x0 Number of IFaces in IFaceMap: 0 Slots in VTable: 7 -------------------------------------- MethodDesc Table...
I am debugging the live process (not dump) of PresentationHost.exe. It used to works fine, but suddenly few days ago I get the above error message. !Threads, !pe, virtually all SOS command doesn't work. All I remember is that I installed Visual Studio 2010 and .NET framework 4.0 before I'm getting that error. Is it related? UPDATE: I ...
I had used SosAssistin past and it was awesome, now I i tried to download it again but it is no longer available :( any other tool which can visually show memory/threads/callstack? ...
The title says it all really. What's the significance of the name "Son of Strike"? Does it serve any meaning or does it just sound cool? ...

I have a windows service that is, intermittently, throwing an exception that sometimes kills its SQLConnection, and other times kills the service completely. It is running live on a customer's site. I have planned to use Windbg + SOS on it to get a crash dump, so that I can debug this at my own leisure. On my first attempt, however, th...
