The problem stems from one of the two (identical) machines drifting off by
60-70 seconds per day. So a few ms here and there are ok.

==================================
Bob,
NTP is normally limited to a +/- 500 parts per million correction - 43
seconds per day. You may be operating outside the range NTP is expecting to
handle. If the clock offset is a stable value of 60-70 seconds per day you
can bias NTP to correct within +/- 500 ppm of that drift.
Cheers,
David
