Today as I was playing a lower level job I was doing some Duty finder. I leveled up and went to the next dungeon. I got an instant pop for Cutters Cry and as DPS this was odd but ok cool. I walked in to an 100% empty instance. This continued for quiet sometime, any attempt to join a group in progress dumped me in the same 'dead' / 'empty' instance.

I had even vote abandoned it myself and it still remained live.

Maybe part of the instance servers crashing problem has to do with instances not being cleaned up / despawned upon completion or abandonment.
