	As Jan says it's best to use a memory debugger of some sort; I would
recommend valgrind - google for it; you need to build ORBit2 with
--enable-purify and run with --alignment=8 but it's an extremely
powerful & useful tool.

	Servants are normally user-instantiated objects, and not CORBA_Objects
- is the above correct ?

	Sure.

	Of course, possibly this is indeed a bug :-) we're fixing a number of
interesting threading bugs in HEAD currenty.

	A better trace using valgrind would prolly be helpful; checking the
servant unref prolly too. A patch to allow shutdown from any thread [
which should be feasible ] would be even nicer :-)

	HTH,
