Here's the thing; I took your advice and kept an eye out for errors related to the debugger support and fixed them when I found them (often with a just quick try except clause as you suggested, I'll revisit them when I get time), there where three locations where the debugger code raised exceptions. After making those changes my application has become significantly more stable. Is it possible that the debugger support code is running all the time, even when a debugger is not attached? (Or that I am missing something and "accidently" running a debugger, IIS is still a bit of a mystery to me). How can I be 100% sure that the debug stuff is disabled? As an example, One thing I have noticed is that I now get "WARNING:Ignoring Keyboard Interrupt from scripting engine" and everything continues as normal, I'm think that producing that warning used to cause a raised exception and kill my app. Does any of this sound feasible? I'm still getting the original access violation (but I am seeing proper debugger output) so there is an issue in my C extension code but the difference in stability is siginificant.
