The thing that can be a problem to believe with such is, based upon how 
long the application has been in use, How could it be considered 
"working"?  There can of course be seldom used parts of the code.

There is the question, what has changed recently?

Lots to look at with such problems, and, if you're like me, usually it's 
the last thing you look at.  Maybe I should say that that it's far down 
the list of things you look at, since when you find it, you stop 
looking, thus the last thing you looked at.
