DNS = 8.8.8.8
Network settings are same in all machines. could any one help me to fix this issue. syslog is having log after every 2 hours.
 
try debugging the DNS-settings on the host - install ldnsutils and run:
Code: 
drill mx noeticworld.com
drill mx noeticworld.com @8.8.8.8
on the node
I hope this helps
