My response is that you're asking the wrong questions here. Our database
server locked up hard Sunday morning, and we still have no idea why (the
machine itself, not just the database app). I think it's more important
to focus on whether you have done all that is reasonable to make your
application reliable -- and then put your efforts into making your app
I'm particularly making this comment in the context of your later point
about the bug showing up only every three or four months.
Side note: without knowing what error messages you're getting, there's
not much anybody can say about your programs or the reliability of
threads for your application.
