We have an MFC dialog based application that has up to 100 threads reading
data from different sources over TCP/IP and then storing the data into an
oracle database. Database updates are realtively infrequent (maybe once or
twice a scond overall). We are having problems with the application just
exiting. Sometimes it will run for days, sometimes for just a few hours.
The user is definitely not exiting the application.
We have try/catch sections around most code and around each thread which
isn't getting triggered and we detect memory allocation failures (which
aren't happening).
Does anyone have any ideas on how we can trace what's causing the
application to exit?
You could install a SetUnhandledExceptionFilter() handler which hopefully
would get executed when the crash occurs. Unfortunately, I'm not sure if
the stack is valid at that point, but you could at least try to shutdown
gracefully and/or restart.
