I get the following message after a few hours running ntp4 (4.0.90f) with
my DCF77 receiver... Is there anything I could do to prevent that ?
Jan 15 21:54:31 tara ntpd[25909]: time error 3600 over 1000 seconds; set clock manually)
After that message, ntpd is gone. Any idea ?
The machine is a 2xPPro/200 with 64 MB RAM, running FreeBSD/SMP from 25th
of December.
