I can confirm that the IP address is not a proxy/router. It is actual address of another machine
I am using. I have tried restarting this machine still I continue seeing these messages in
the zookeeper log.

According to your logs,it seems that error doesn't relate to ZK dataDir.
But you have some client trying to reconnect using old session(it saw
last zxid 0x50a83 which is invalid now because you remove dataDir and zxid was reset).
But, you point that machine was shutdown. Can you clarify that IP
is a real machine IP and not a some proxy/router?

I am new to Zookeeper. I was playing with a single node Zookeeper 3.4.6 shipped with Apache
Kafka 0.10.

I was facing some connection issues to Zookeeper hence I decided to stop it, clear all state
(by deleting the dataDir) and start it back up. However after it comes back up, I can see
it log the following lines continuously on the console:

[2017-01-28 01:36:44,312] INFO Accepted socket connection from / (org.apache.zookeeper.server.NIOServerCnxnFactory)
[2017-01-28 01:36:44,313] INFO Refusing session request for client / as it has seen zxid 0x50a83 our last zxid is 0x1b client must try another
server (org.apache.zookeeper.server.ZooKeeperServer)
[2017-01-28 01:36:44,313] INFO Closed socket connection for client / (no session established for client)

What is really strange is that I keep seeing this even though the machine with IP
has been shut down!

What am I missing? I have tried restarting zookeeper and clearing the data directory several
