This is a curious monster; it can't decide if it wants to be an ADT or an ASM, 
and queues with negative depths seem to be meaningful. However, there is nothing 
about it that would seem likely to cause a memory leak. It might have something 
to do with where and how it is instantiated, or perhaps the types used to 
instantiate it.

GNAT has GNAT.Bounded_Buffers, or you could use something from one of the many 
fine libraries of Ada components available, like 
PragmARC.Queue_Bounded_Blocking. They have more coherent designs and a better 
grasp of the issues involved in Ada concurrency.
