Hi,
I have some "flapping" in ntp on soekris.
Is it important ?
First soekris (auto reboot each 15 and 45 minutes)

I have some other soekris, and I never have so many log message. On
these others box there are a "adjusting" message once by week or once
a day.
There are too many back and forward adjustements too close in time.
Notice: The auto reboot is done by cron. I just do that because I
test my redundant firewall.
I may accept that during reboot the RTC lost it accuracy
But if I take a slice a 30 minutes between 2 reboots, there are
strange thing:
Jun 8 09:47:46 r001 ntpd[23319]: adjusting local clock by 0.875716s
Jun 8 09:51:26 r001 ntpd[23319]: adjusting local clock by 0.816038s
Jun 8 09:55:43 r001 ntpd[23319]: adjusting local clock by -0.320128s
Jun 8 09:59:52 r001 ntpd[23319]: adjusting local clock by -0.695182s
Jun 8 10:01:35 r001 ntpd[23319]: adjusting local clock by -0.338598s
Jun 8 10:05:18 r001 ntpd[23319]: adjusting local clock by 0.156039s
It looks like the correction may have been done twice (0.875716s and
0.816038s)
Too much in one direction, then (-0.320128s, -0.695182s, -0.338598s)
The sum of the 5 first lines is 0.338s
Same things with
