Friends, we are using ADPlus (CDB) to log w3wp.exe things are part of our
debugging efforts. A log file gets filled with TONS of "1st chance
AccessViolation" exceptions. Is this to be expected? Or, is this
indicative of some flaw that we need to fix. THings keep running, and we
never see "Second Chance", so I guess somebody is catching this stuff.
Your thoughts will be very much appreciated. Thanks in advance!

yes, its probably bad. the error is occurring when asp.net is trying to
release a com obect, but the com object is blowing chuncks. its after page
processing so your pages don't see it. who knows what unmanged memory looks
like or if your leaking

Interesting. Is this true?
The developers in-house were convinced this was normal MFC-related stuff
when used in a windowless context, such as when hosted under w3wp.exe or
something.
We are having other issues related to critical sections (not our own, but
possibly ODBC or CRecordset internal ones) that don't get released, and
folks end up blocking waiting. The entire app basically stops, at least as
far as users are concerned.
Any clue on ow we meight proceed? I've been using AD-Plus (CDB) and
IISState to look at the guts of w3wp.exe after these "hangs, and these tools
have helped us rule out some things. But, these "1st chance
AccessViolation" messages might be a clue.
James
I've used past version of CRecordset in a middle tier component
without problems - at least not related to the MFC stuff itself. I
think we took ATL project templates and added support for MFC
libraries.
Are you reproducing the problem in a development environment?
Can you ask the debugger to break "when the exception is thrown"
(Debug - > Exceptions dialog box) instead of breaking when an
exception goes unhandled (the default)? Just throwing out an idea.
