i'm still trying (and failing) to solve a large-jitter problem.
in various troubleshooting, i've noticed the frequent appearance of
the number "3.906".
e.g., right at launch,
Wed Oct 14 09:16:26 2009
assID=0 status=c011 sync_alarm, sync_unspec, 1 event, event_restart,
version="ntpd [email protected] Fri May 8 08:40:54 UTC 2009 (1)",
processor="x86_64", system="Linux/2.6.27.29-0.1-default", leap=11,
stratum=16, precision=-8, rootdelay=0.000, rootdispersion=0.000, peer=0,
refid=INIT, reftime=00000000.00000000 Wed, Feb 6 2036 22:28:16.000,
poll=6, clock=ce809b7a.ed889f44 Wed, Oct 14 2009 11:48:26.927, state=1,
---> offset=0.000, frequency=-3.502, jitter=3.906, noise=3.906,

and a couple of hours later,

i'm guessing this is not coincidence ...
is it indicative of any problem?
thanks.
