I'm guessing here, but I think this problem can be
caused by closing a file that is opened with GET_LUN
with the CLOSE command, rather than by closing the
file and freeing the logical unit number with FREE_LUN.
(Note: FREE_LUN performs *both* actions. There is no
need to use CLOSE with it.)

Other programs must be checking for attached logical
unit numbers is what I am thinking.

Cheers,

David
