Hi guys,
I'm totally confused by this series of snapshots below. Running 4.2.4p3
under NetBSD-3.1/patch, I started seeing some strange steps this morning.
I added some logging instructions in ntp.conf and restarted the daemon,
and the steps keep happening.
First, here are some billboards, showing things progressively getting out
of hands. I snipped the refid column to avoid wrapping.

Finally, here is ntp.conf. Let me know if I should change to improve
logging and give you guys some information to understand what's going on?
pidfile /var/run/ntpd.pid
driftfile /etc/ntp.drift
keys /etc/ntp.keys
statsdir /var/NTP
logconfig =allsys =allpeer =allsync
trustedkey 1
controlkey 1
requestkey 1
server bonnie.concordia.ca iburst
server ntp.uqam.ca iburst
server ntp1.cmc.ec.gc.ca iburst
server time.nrc.ca
server time.chu.nrc.ca
server sylvester.sraq.qc.ca
statistics loopstats peerstats sysstats
enable stats
restrict localhost
restrict 192.168.2.0 mask 255.255.255.0
restrict default nomodify
Other than the logconfig and statistics parameters I adjusted this
morning, I've been running this configuration for months now without a
single step happening. The network configuration hasn't changed either
(same router and firewall rules as before).
Any ideas?
