[ntp:questions] Flash 400 on all peers; can't get ntpd to be happy

I'm trying to get my ntpd configuration to work and no matter what I try nothing seems to work.

I have numerous servers configured (and have tried various ones) in addition to pool servers and still can't get a configuration that works cleanly.  When I run the peer command, all the servers display a condition of 'reject' and a status of 9014.  If I run a pstatus on them I get a flash value of 400 and results that look like this:

assID=39606 status=9014 reach, conf, 1 event, event_reach,
srcadr=caprica.lerfjhax.com, srcport=123, dstadr=,
dstport=123, leap=00, stratum=2, precision=-20, rootdelay=36.652,
rootdispersion=24.139, refid=, reach=377, unreach=0,
hmode=3, pmode=4, hpoll=6, ppoll=6, flash=400 peer_dist, keyid=0, ttl=0,
offset=67671.865, delay=79.190, dispersion=8.719, jitter=4952.046,

filtoffset= 67671.8 66534.8 65931.3 65118.0 63317.3 63029.5 62216.4 58156.6,

I've tried removing all the restrict statements from my config to no avail.  When I run peer my reach values are at 377 which I am to understand is an indication that things are ok in one respect.  Yet I seem to be stuck in this status where I'm getting time information but not able to get a status that is 'happy'.  My rv results always look something like this...

assID=0 status=c011 sync_alarm, sync_unspec, 1 event, event_restart,
version="ntpd 4.2.2p1 at 1.1570-o Sat Dec 19 00:58:16 UTC 2009 (1)",
processor="i686", system="Linux/2.6.18-194.32.1.el5", leap=11,
stratum=16, precision=-7, rootdelay=0.000, rootdispersion=30.540,
peer=0, refid=INIT,
reftime=00000000.00000000  Wed, Feb  6 2036 22:28:16.000, poll=6,
clock=d11d6d3b.ea5a48ed  Sat, Mar  5 2011 18:17:31.915, state=1,
offset=0.000, frequency=8.747, jitter=7.812, noise=7.812,
stability=0.000, tai=0

Now I know the clock on this machine isn't very accurate and I've had to set the tinker panic 0 in my config so that ntp can move the clock forward by large chunks, but does that prevent my ntpd from working cleanly?

I'm on ntp-4.2.2pl-9 on CentOS.

Thanks in advance to anyone that can offer assistance.
