We've recently started having an issue where all of our app pools set to .NET 2.0 and Integrated mode are crashing immediately upon starting.
Nothing makes it to the IIS log, but the HTTPERR log shows the same thing every time:
Line 2084: 2013-11-15 01:33:39 10.71.21.242 57020 192.168.16.26 80 HTTP/1.1 GET / - 129 Connection_Abandoned_By_ReqQueue test
I've run DebugDiag and hit the site, and get back some relatively useless info as far as I can tell:
In w3wp__test__PID__5196__Date__11_14_2013__Time_03_16_34PM__253__Second_Chance_Exception_E0434352.dmp the assembly instruction at KERNELBASE!RaiseException+3d in C:\Windows\System32\KERNELBASE.dll from Microsoft Corporation has caused a CLR Exception on thread 8

I am unable to run WinDbg on this as I can't get to the process fast enough before it crashes.
I'm not really sure what could be causing these with these two specific settings set (if I change to .NET 4.0 -OR- change to Classic mode, sites will work).
Worth noting too: This is happening independant of the site running in each app pool - it's happening for Sitecore, Umbraco and static sites (including a hello world app)
