Jason Huynh commented on GEODE-5565:
------------------------------------
If a region is destroyed during gii, there is a chance that we have allocated
memory for off heap for the entry, but end up not being able to set the value.
This bubbles up but never releases the memory.
> Release off heap entry during gii if Region has been destroyed
