For Debug Diagnostic 1.2, please refer to
This article will detail the action plan you can implement to generate a manual hang dump using Debug Diagnostic for a specific process. In this case we will focus on the W3WP.exe process corresponding to your Application Pool in IIS that is experiencing a hang.
This action plan can be applied when your W3WP.exe process or your application is hanged and that you are quickly aware of the situation to generate a dump yourself before the issue is gone. A hang of a process means the application is no longer responding within a normal execution time or is even not responding at all but the process is not crashing. This means there is no stop or restart of the process and you won't see any change to the Process ID.
If the operating system is 32-bit, install the 32 bit DebugDiagx86.msi. For 64 bit operating system choose the DebugDiagx64.msi.
The dumps are located by default in "C:\Program Files\DebugDiag\Logs\Misc".
This location can be modified by using the "Tools > Options and Settings…" menu, via the field "Manuel Userdump Save Folder".
