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 times.
