If a cluster has leafnode connections and each have the same queue group, the loss of a leafnode connection could cause the server in the "hub" cluster to drop interest across a gateway for this queue group. The issue is fixed by properly accounting for all queue sub and unsub in the server gateway interest map. Signed-off-by: Ivan Kozlovic <ivan@synadia.com>
