If you want to use WinDBG, this is probably a good start: http://www.adopenstatic.com/cs/blogs/ken/archive/2009/06/30/24910.aspx
Dump a list of threads and see which are the longest running Then dump the managed and unmanaged stacks for those threads. The problem then is that you need to know what you're looking at. You can post some here if you want or at forums.iis.net Cheers Ken From: Sobey, Richard A [mailto:[email protected]] Sent: Friday, 5 April 2013 9:37 PM To: NT System Admin Issues Subject: RE: Analysing process dumps Oh, wonderful, thanks. I tried windbg, but yes, the output is a bit mystifying and I'm not sure what I'm looking for. Thanks Ken Richard From: [email protected]<mailto:[email protected]> [mailto:[email protected]] On Behalf Of Ken Schaefer Sent: 05 April 2013 11:19 To: NT System Admin Issues Subject: RE: Analysing process dumps IIS Debug Diagnostics tool does a bunch of things for you automagically, and is geared towards w3wp.exe issues. Otherwise you can simply download the Windows Debugging Toolkit (the main tool you want is WinDBG), or use any user mode debugger (even Visual Studio.Net) if you want to try to root cause yourself However actually understanding what you are looking at requires some knowledge (plus some knowledge of how the tool works) Personally, I would use IISDebugDiag, and post the output to forums.iis.net - a bunch of MS PSS folk and MVPs hang out there, and if they can't help you within bounds of reason, they will direct you to PSS support if required.

I'm creating process dumps, as I saw suggested on a forum, but is there any tool that can usefully analyse the output without me opening a case with Microsoft PSS?
