From time to time I get questions about missing method names in the sos !clrstack output, like this: 0:019> !clrstack OS Thread Id: 0x5d0 (19) ESP EIP 0f31f340 7c80bef7 [HelperMethodFrame_1OBJ: 0f31f340] 0f31f398 1449167a 0f31f3c4 144915e6 0f31f3f4...

I recently got a question about if it is possible to generate full user mode dumps automatically every time the process crashes (without having debug diag or adplus installed and monitoring your system). This would be useful for example if you are setting...

I have written before about high memory usage caused by improper usage of XmlSerializer objects both in a case study and in a debugging lab .  The problem there was that every time you create a new XmlSerializer object with a non-default constructor...

It’s been a pretty busy few weeks at work coupled with some vacation so I’ve been lagging a bit with the blogging, so sorry for bombarding the blog with new posts now:) As you all know, Visual Studio 2010 just released and there is a lot of new content...

I was helping out on an issue the other day where the process would stall if they added enough users in their load tests.  Btw, serious kudos to them for making load tests, so much nicer to work with a problem in test rather than when it is getting...

I recently got a question by one of my customers about PAE and IIS that I thought I’d share the answer to. Their environment looked something like this: 32bit OS (Windows 2003) IIS 6 with multiple application pools, where each app pool hosts a number...

Tom just blogged about a new debugger extension called PSSCor2, which is a superset to the SOS.dll extension that ships with the .net framework. PSSCor2.dll has been around for quite some time at Microsoft, and pretty much everyone debugging .net code...

Just a quick post to share a link to last years videos for the Oredev developer conference http://oredev.org/video Here is my .net debugging presentation where I show off some windbg + new VS.NET features and apart from all the good developer content...

Visual Studio.NET 2010 has a new feature that allows you to create nice directed graphs with a markup language called DGML (Directed Graph Markup Language).  Visualizing object graphs with DGML Chris Lovett wrote a tool that takes GCRoot output and...

My friend and fellow debugger Brian at http://Kodehoved.dk recently wrote a couple of posts on news with sos for .NET framework 4.0 (in Danish) New SOS Commands in .NET 4 More debugging news in CLR 4 Since Danish, although a beautiful language is probably...

March 23rd and 24th I will be presenting at TechDays Sweden in Örebro.  The agenda for my session is not set in stone yet but the plan is to talk about debugging .NET production type issues as usual (Performance, Memory, Crashes, Exceptions etc....

If you have a .NET configuration file with multiple <setting> elements, you may get the following exception: Unhandled Exception: System.Configuration.ConfigurationErrorsException: Unrecognized element 'setting'. (F:\MyApp\bin\Debug\MyApp.exe.config...

MSDN Radio is a Swedish MSDN podcast that is Dag König puts together every other week.  The show contains a number of different segments and is usually pretty fun to listen to. Starting this week, and hopefully every other week or so during the spring...

I often get questions about debugging native memory leaks. In other words, cases where you have high memory usage in your application but you can see that .net memory usage is not all that high. Recently I was helping out on such a case and this post...

A couple of weeks ago I helped out on a high CPU issue in an ASP.NET application. Problem description Every so often they started seeing very slow response times and in some cases the app didn’t respond at all and at the same time the w3wp.exe process...

Last week i got the new Advanced .NET Debugging book by Mario Hewardt (co-authored with Daniel Pravat) in the mail.  I had the pleasure of tech reviewing it earlier this year and it is a really good deep dive in .net debugging and .net internals...

I just returned from Oredev and TechED EMEA , both conferences were very interesting in their own special ways. TechED was of course bigger with a lot of good sessions on my specific area while Oredev is a bit more small and cozy, and a way to meet people...

This week I attended and spoke at the Oredev conference in Malmö Sweden, and it was great fun as usual. It was a pretty productive few days with a lot of good talks and conversations with some really cool people. I’ll put up a link to the talk as it becomes...

For all of you who have been asking me if there is a 64bit version of Debug Diag (used to debug 64 bit processes), I am happy to say that yes, Debug Diag 1.1 64bit is now released. You can download it here: http://www.microsoft.com/DOWNLOADS/details.aspx...

I had an interesting case today where an asp.net app was stuck in a true deadlock. In other words two threads were both waiting for resources that the other thread owned. The scenario in these cases usually goes something like this: FunctionA (locks on...

I got an email today on an issue that I think is pretty common when you try to memory leak analysis on a dump with debug diag . They had set up a leak rule in debug diag to monitor for leaks and then ran the memory analysis on it to see what was leaking...

I was out looking for some sample scripts for tinyget and ran across this ANTS Memory Profiler review where Scott Seely has tested it out on some of my debugging labs . I haven’t had the time and/or opportunity to test it out myself but since many people...

The other day I came across an issue where an ASP.NET site stopped responding and didn’t start serving requests again until the W3WP.exe process was restarted. We grabbed some memory dumps with debug diag before restarting the process to see what was...

TechED Europe – Berlin -  9-13th of November This will be the 2nd time I present at TechED. Last time I had an absolute blast and heard some really  good speakers. I am still working with the TechED team on exactly what type of sessions I will...
