-------------------------------------
Reference : https://builds.apache.org/job/ZooKeeper-3.4-WinVS2008_java/416/
I've done intial analysis and please see the life span of the session
0x143b92b03330000:
+Phase#1 :+ Here it has established the connection
{code}
[junit] 2014-01-22 08:57:20,683 [myid:] - INFO [main:ZooKeeper@438] -

0x143b92b03330000, negotiated timeout = 30000
{code}
+Phase#2 :+ Here it shows the client is not able to get the response from the
zk server
{code}
[junit] 2014-01-22 08:57:20,740 [myid:] - INFO [main:JMXEnv@113] -

additional data from server sessionid 0x143b92b03330000, likely server has
closed socket, closing socket connection and attempting reconnect
{code}
+Phase#3 :+ Here the client is trying to renew the session 0x143b92b03330000,
but sees an expiration.
{code}
[junit] 2014-01-22 08:57:23,488 [myid:] - INFO

[junit] 2014-01-22 08:57:23,489 [myid:] - INFO
[main-SendThread(127.0.0.1:11232):ClientCnxn$SendThread@1087] - Unable to
reconnect to ZooKeeper service, session 0x143b92b03330000 has expired, closing
socket connection

{code}
I think, the server has closed the session 0x143b92b03330000 and removed the
connection. From the logs, I couldn't see more information about expiration or
session closure that has occured in the zk server.
