> When we run our Distributed system Model Checking (DMCK) in ZooKeeper v3.5.3
> by following the workload in ZK-2778:
> - initially start 2 ZooKeeper nodes
> - start 3 new nodes
> - do a reconfiguration (the complete reconfiguration is attached in the document)
> We think our DMCK found this following bug:
> - while one of the just joined nodes has not received the latest configuration update

> (called as node X), the initial leader node closed its port, 
> therefore causing the node X to be isolated.
> For complete information of the bug, please see the document that is attached.
