Hello all. This question is fairly straightforward -- I am trying to debug a memory leak in a silverlight application using s.o.s. I was able to get some good info using !gcroot to determine what objects have open references to the one that should be getting cleared; but in these cases they tend to be core UI elements (like grid and st...
I'm looking into why a managed process is using a lot of memory. Is there a way to run GC.Collect(3) from WinDbg, so that I can focus on the actual memory allocation? ...
I'm using Windbg (with the sos extention) and trying to debug a crashed application. I was able to dump the IL of the call that threw the exception and by examining the code, it seems like I could obtain the information that I need if I could dump the contents of the evaluation stack. Is it possible to do what with WinDbg & sos ? Here...
I have a managed code Windows Service application that is crashing occasionally in production due to a managed StackOverFlowException. I know this because I've run adplus in crash mode and analyzed the crash dump post mortem using SoS. I have even attached the windbg debugger and set it to "go unhandled exception". My problem is, I can'...

VS2005 C# Compiler crashes during our team's nightly build process. I attach to it with WinDBG, load SOS extensions, print the callstack, but cannot see exception info. I tried !PrintException, as follows: 0:000> !PrintException There is no current managed exception on this thread Here's the top of callstack: 0:000> !...
I just started using cdb and I love it! I've found and bookmarked a few interesting articles I've found on using cdb, but I'd love to see other peoples resources. What sites do you use to extract the max usefulness from cdb (windbg) ...
I think I'm missing some fundamentals here so hopefully this post can clarify this. I've taken a dump and am looking at the managed heap and am interested in looking specifically at what objects are within each heap. Here is the output from the debugger: 0:000> !eeheap -gc Number of GC Heaps: 1 generation 0 starts at 0x3cca447c generat...
The documentation on the SOS.dll Windbg extension seems sparse. After issuing a !gcroot <address>, I am getting something containing the following: DOMAIN(XXX):HANDLE(Pinned):XXX:Root:XXX(System.Object[])-> Does "HANDLE(Pinned)" really mean there is a GCHandle of type GCHandleType.Pinned that is rooting this object? ...
I'm a newbie with WinDbg and got this dump from the WER ReportQueue folder on a 64-bit Windows 2008 Server. I need to examine the dump and want to do so on my developer machine on which I've installed the Debugging Tools for Windows package. When I try to load SOS I got the following error which I've never seen before: 0:035> .loadby so...
Is there any way to tell SOS to merge all the latest files in a given branch into the trunk? I've checked out all the files that are going to change. I can merge single files by selecting the latest branch revision and using the Revision->Merge menu command. However, the option is greyed out if I select more than one file. I've quite ...
When I use .load SOS in Visual Studio's immediate window and accitentally issued a command that result in a long list of output (e.g. !dumpheap -type System.String -min 100), the immediate window just can't stop listing the values and keeps scrolling for hours. All I can do is kill the process and restart debugging. This is very annoying...
From within visual studio immediate window with SOS debugging extension loaded I can do !dumpheap -stat Then I get something like this: total 108,014 objects Statistics: MT Count TotalSize Class Name ... 0x00be209c 135 714108 System.Object[] 0x79b925c8 218 2659728 System.String 0x00be2c3c ...
I am investigating what is taking up lots of memory in my app. Using the !DumpObj command, I can get around the managed objects. But how do I do the equivalent for native objects? For example, this .NET object has a pointer to native code. I am stuck here... how do I do the equivalent of !DumpObj from here? I have all the source and...
Here is my scenario: Start my test program and immediately break into the debugger (WinDBG) Take a !DumpHeap -stat and observe there are no System.Net* or System.Xml* objects anywhere Create my WCF client, make a WCF request Close the WCF client and force GC. Take a !DumpHeap -stat and observer there are tons of System.Net*, System.Xml...

Is it possible, while debugging a Silverlight app, to view all current references to an object? I know that WPF developers have the ability to use the SOS.dll, but that cannot be loaded in the VS2008 IDE while debugging a Silverlight app. I've tried it, but the load command gives me the error: .load C:\Program Files\Microsoft Silve...
