Hi!

Noticed periodical messages in logfile:

Dec  8 11:33:38 time ntpd[7000]: kernel time sync disabled 2307
Dec  8 11:33:55 time ntpd[7000]: kernel time sync enabled 2107
Dec  8 11:42:56 time ntpd[7000]: kernel time sync disabled 2307
Dec  8 11:43:13 time ntpd[7000]: kernel time sync enabled 2107
Dec  8 11:48:21 time ntpd[7000]: kernel time sync disabled 2307
Dec  8 11:48:36 time ntpd[7000]: kernel time sync enabled 2107

 From status bits I understand that it means "PPS signal jitter exceed", 
but why?
Is it normal (safe)? How to found reason?

Using Garmin GPS18 LVC, FreeBSD 4.2, ntpd 4.2.0-a

time# ntpq -p
     remote           refid      st t when poll reach   delay   offset
