ntpd has suddenly broken out into oscillations. it is fed by a Garmin 18 LVC PPS via shm. The oscillation has a period of just under an hour ( about 50 min) and an amplitude of about 10usec. in the offsets ( amplitude of about .005PPM in the rate). Since this is acting as the clock for a number of other machines, they are also showing the oscillation especially in the rate. While I suppose this could be something in the GPS itself, it looks more like an oscillation in ntpd. Nothing changed when the oscillations started. Ntpd had been started on Dec 14, and this change began on Dec24. You can see the graph on www.theory.physics.ubc.ca/chrony/chrony.html , the graph for the machine called string.
Has anyone else ever seen this kind of thing? _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
