Missing or Stuck Network Queue Consumers in Network of Brokers with conduitSubscriptions Disabled

In a network of brokers configured for balancing, similar to the attached configuration, when local consumers are added or removed, the network subscription count is not consistently reflected. It appears that both new and delete subscription advisories are sometimes either missed or suppressed with the result that not all live consumers get a remote consumer on the bridge and when all local consumers are shut down (no local consumers on any broker in the NOB), we still see consumers on the bridge, resulting in forwarding behavior when no actual demand exists on the other side of the bridge.

This is occurring with no pendingMessageLimitStrategy applied. It seems to occur more frequently if suppressDuplicateQueueSubscriptions=true, but has been observed to occur without this flag set, as well.
