In a deployment of 3 Node Zk Cluster we have seen that sometime port 3888

Don't leader itself should come out of clustering if this happens ??
I'm not well-versed in how ZK works internally, and don't have access
any more to systems I can check, but I seem to remember when looking at
a live ensemble that not every ZK instance will bind to all three ports
(2181, 2888, and 3888 if using the example configs). Surprised me when
I noticed it, but I didn't worry about it too much since ZK seemed to be
working correctly.
