Dump Diagnostics

I solved my problem in 5 steps:

1) I installed a software to get a crash dump. In this case i downloaded the DebugDiag Tools.

2) I configured the DebugDiag Tool following these instructions in this post . I didn't need to install WindDbg and Symbols.

After the installation it was configured in this way:

• Selecting a Crash rule
• Selecting a IIS App pool (w3wp.exe)
• Selecting the app pool of my application
• Configuring a Stack over flow exception (0xc00000fd) in Advanced Settings/Exceptions and finishing the setup.

3) I waited for a first crash dump to be created in a folder location. Ex: C:\DebugDiag\Logs When the crash dump was created, i used the DebugDiag Analysis to open the file from C:\DebugDiag\Logs and a HTML report has been created.

4) In report was easy to see the problem. In my case, there was a recursive function without stop conditional. It was crashing the w3wp process.

5) Our team fixed the bug and solved the problem

What you have tried is less relevant.

0xc00000fd means stack overflow. Thus, you need to review your code to see if it was caused by yours. If you were able to get a crash dump, that can provide more information about why it crashes.
