xntpd daemon keeps on dying

MoloisD — Fri, 08 Sep 2006 04:00:03 GMT

Hi

On HP11.11 server my xntpd daemon keeps on dying every 5 - 10 minutes.
I rerun the ff command to restart:
/usr/sbin/xntpd

Currently the server is 27 min behind the ntp server.Below is the error message on syslog.log
What could be the cause?

" Sep 8 10:20:38 uxerfmsp xntpd[27045]: synchronized to 10.1.48.9, stratum=2
Sep 8 10:20:38 uxerfmsp xntpd[27045]: time error 1651.285736 is way too large (set clock manually) "

Your help will be much appreciated
Thanks

Too much of time difference that NTP can adjust. You can first set time manully to that of server (but note than this may cause problems to applications/programs that are time sensititve. So shut them down if you can)

Once you sync time, then ntp should run without problems.

you can sync time to the server as
ntpdate "ntp_server"

This is normal and documented behavior. The maximum time offset is 1000 seconds and if that is exceeded then the daemon shuts itself down. In your case, you should stop any critical applications, especially databases, then manually set the date using the date command, and then restart the ntp daemon. All should be well and the systems should then remain in sync.

The error message is telling you exactly what the cause is:

Sep 8 10:20:38 uxerfmsp xntpd[27045]: time error 1651.285736 is way too large (set clock manually) "

The time difference of 1651.28 seconds is too large for NTP to deal with. You need to first set the clock manually and then start NTP so it can synchronize it.
