NTPD issues

I have a centos 4.6 machine with ntpd issues;
ntp-4.2.0.a.20040617-6.el4. Actually I think most, but not all, of my
centos 4.6 servers are having this problem. My RHEL and ubuntu
machines seem fine.

While the machines in question seem to be syncing their own clock,
they're not advertising to clients properly:

ntpq> rv
assID=0 status=c644 sync_alarm, sync_ntp, 4 events, event_peer/strat_chg,
version="ntpd 4.2.0a@1.1190-r Sat May 5 12:55:34 EDT 2007 (1)"?,
processor="i686", system="Linux/2.6.9-34.0.2.ELsmp", leap=11,
stratum=16, precision=-20, rootdelay=0.000, rootdispersion=4.770,
peer=55545, refid=INIT,
reftime=00000000.00000000 Wed, Feb 6 2036 22:28:16.000, poll=6,
clock=0xcbb0adc4.9431df76, state=3, offset=37.226, frequency=0.000,
noise=28.774, jitter=12.528, stability=0.000

The reftime stays in the future and the stratum at 16. I've pared
down the config file to be as simple as possible and most recently
added a bunch more servers:

driftfile /etc/ntp/drift
server 127.127.1.0 # local clock
fudge 127.127.1.0 stratum 10
server 0.ca.pool.ntp.org. iburst
server 1.ca.pool.ntp.org. iburst
server 2.ca.pool.ntp.org. iburst
server 3.ca.pool.ntp.org. iburst
server 0.us.pool.ntp.org. iburst
server 1.us.pool.ntp.org. iburst
server 2.us.pool.ntp.org. iburst
server 3.us.pool.ntp.org. iburst
server 192.168.24.3 burst

It seems to be synchronizing properly, it says there is one syspeer
and 4 more candidates:

ntpq> lpeers

Does anyone have suggestions? And yes I wait up to ten minutes after
a restart to ensure it has time to do its thing. There is no
firewall. Thanks.
