I still get this error on Ubuntu 10.04 LTS (latest updates), under 'cold start' conditions.
For example: (new host), install ntp (sudo apt-get install ntp) ~$ ntpq -c rl (on a different host) associd=0 status=c011 leap_alarm, sync_unspec, 1 event, freq_not_set, version="ntpd 4.2.6p2@1.2194 Fri Sep 2 18:37:15 UTC 2011 (1)", processor="i686", system="Linux/3.0.0-12-generic-pae", leap=11, stratum=16, precision=-20, rootdelay=0.000, rootdisp=0.420, refid=INIT, reftime=00000000.00000000 Thu, Feb 7 2036 19:28:16.000, clock=d26c2106.4ae705a8 Tue, Nov 15 2011 12:21:42.292, peer=0, tc=3, mintc=3, offset=0.000, frequency=0.000, sys_jitter=0.000, clk_jitter=0.001, clk_wander=0.000 sometime after install, BUT before it is properly synced, I may get: ~$ ntpq -c rl assID=0 status=c644 sync_alarm, sync_ntp, 4 events, event_peer/strat_chg, version="ntpd 4.2.4p8@1.1612-o Tue Apr 19 07:08:29 UTC 2011 (1)", processor="i686", system="Linux/2.6.32-34-generic", leap=11, stratum=16, Segmentation fault later still, when properly synced, it returns valid data: ~$ ntpq -c rl assID=0 status=0664 leap_none, sync_ntp, 6 events, event_peer/strat_chg, version="ntpd 4.2.4p8@1.1612-o Tue Apr 19 07:08:29 UTC 2011 (1)", processor="i686", system="Linux/2.6.32-34-generic", leap=00, stratum=3, precision=-20, rootdelay=303.768, rootdispersion=75.598, peer=65450, refid=91.189.94.4, reftime=d26c181d.ef314855 Tue, Nov 15 2011 11:43:41.934, poll=6, clock=d26c187f.d8e7310b Tue, Nov 15 2011 11:45:19.847, state=4, offset=21.891, frequency=86.577, jitter=24.303, noise=46.878, stability=25.729, tai=0 This must relate to string-space, a negative value (unexpected), or similar for nonsense data.
