initially when the agent is up, the ssh connection is up and running.
root@4b1fc42506f3:/# netstat -na | grep 111.11.11.3
tcp6 0 0 172.17.0.11:46562 111.11.11.3:830 ESTABLISHED
root@4b1fc42506f3:/#

when we stop the agent (netconfd) alone, they enter into TIME_WAIT state

root@4b1fc42506f3:/# netstat -na | grep 111.11.11.3

tcp6 0 0 172.17.0.11:46565 111.11.11.3:830 TIME_WAIT

tcp6 0 0 172.17.0.11:46562 111.11.11.3:830 TIME_WAIT

after sometime when we bring the netconfd up again, these disappear
there is no reconnection

root@4b1fc42506f3:/# netstat -na | grep 111.11.11.3

root@4b1fc42506f3:/#

When sshd is restarted the reconnect seems to work fine. But not in this case.
