I have a few very hard hours for me before I found a problem.
Thanks to Tess Ferrandez and her blog post I found it.
Always double check Your multithreaded code in asp.net application. When Unhandled exceptions occurs application pool crashes and it's damn hard to find WHY.

Tess's blog was a little advanced for me. I had to search around for quite a bit before I found the right articles that helped me debug my dump files. This article will help others who want to debug their crashing asp.net application pools but don't know how to start.
