ntpd is getting stopped frequently on linux box

[E.Gopi Kannan]

Please your help on this....

In linux server, the ntpd service is getting stopped frequently...

How to resolve this issue.?

There are a number of reasons for this. Firstly that time on the reference clock that you are syncing with is too different. This generates a "clock-insane" message which panics ntpd.

Second, the reference clock process is running a different version of the protocol.

The best thing to do is to stop ntpd on the client and run ntpdate to force the times to sync, then start ntpd and keep running ntpq -p to check how the sync is working.

Dependant upon your version of ntp it is also possible to run in debug mode and to capture the messages that are being exchanged.
