There was some problem with A340/330 APUs ..(I think one or two
have caught fire on the pax aboard)
but I've read they have been or are being replaced (with restricted ops
until replacement).
As someone else said, the `ghost in the machine' you describe
can be extraneous to the APU and more to do with the passenger
amenity systems.  I was recently on an Air Canada 767-300 and
the `fasten seat belt' chime kept going off uncontrolled
at random (`Sorry, nothing we can do, sir') ALL NIGHT LONG
(trans-Atlantic flight).
