ASP.NET Web App freezes exception, dw20.exe hangs on 100% CPU

Apologies for the openness of this question, but I really don't know what to say.

I did something for my ASP.NET MVC web application to throw an exception, which is probably due to a NHibernate mapping error, to get dw20.exe to work at ~ 50% CPU usage (100% on one core) , The browser does not respond until IIS expires and the debugger never gets an exception, everything just hangs: s

Anyone have any ideas on where to start?

I am on a Windows 2008 server, vs2008, .net 3.5

Edit: multiple found in eventlog

Application error w3wp.exe, version 7.0.6001.18000, time stamp 0x47919413, kernel32.dll error module, version 6.0.6001.18215, time stamp 0x49953395, exception code 0xe053534f, error offset 0x000442eb, process identifier 0x% 9, application startup time 0x% 10 .

thanks

Andrew
