In complex situations, queue members count across various servers may not be properly accounted for when sent to a new leafnode connection. The new test TestLeafNodeQueueGroupWithLateLNJoin has a drawing of such setup, when after LN1 joined, and then queue members were removed with 1 left, LN1 was told that there was no more interest, so message published to LN1 would not reach the remaining queue sub connected to LN2.
