The only other thing I've experienced that hasn't been mentioned in this thread is if an item gets stored in a different frame than what it was supposed to use. Thus LIST FILE would show it but SORT FILE would not. That was in the early 1980's and microdata called it a 'database failure'.
Fortunately my expertise in GFE's has been retired due to the contemporary file systems virtually eliminating these problems, although I still have a few native and 2 microdata clients left who haven't converted yet. I probably touch 1 GFE per year total with these 4 old-school systems.
