NTPD service is deleting and enabling the network
 

Ntpd daemon is deleted the interface, and because of this i am unable to connection to that machine. Only after manually restarting the network service, i am able to connect it. Logs are as follows

ntpd can not take down your network. that's it most likely responding to the ntpd process restarting. it is not deleting the interface itself, but it's hook to it.

Im facing the same exact issue..whats the solution ?

kernel: lo: Disabled Privacy Extensions
ntpd[27127]: Deleting interface #5 eth0, 10.52.17.119#123, interface stats: received=1539, sent=1544, dropped=0, active_time=456059 secs
ntpd[27127]: Listening on interface #6 eth0, 10.52.17.119#123 Enabled
init: tty (/dev/tty1) main process ended, respawning

That's not an ntpd issue, it's just responding to something else going on.
