Issue/Introduction

Agent losing connectivity intermittently below is the error message 

Caused by: java.net.UnknownHostException: <hostname>
  at java.net.AbstractPlainSocketImpl.connect(Unknown Source)

Cause

DNS fails to resolve the hostname and to find out cause internal network teams should troubleshoot using traceroute,etc.

Resolution

- work-around is to keep the host information in /etc/hosts file in server for a direct handshake with the server from agents.

- Make sure that DNS is resolving correctly.
