NTP daemon works for a bit, then "ntpd dead but subsys locked"
I have just installed RH 7.1 and am trying to get NTP to manage my clock.
Out of 8 RH 7.0 and 7.1 installs , I am batting just above 0.500 with NTP.
Once I added a valid server to the npt.conf, I entered /etc/init.d/ntp
start. The daemon responds with an ok. If I then perform a /etc/init.d/ntp
status after five minutes, I receive the following message: "ntpd dead but
subsys locked". Of course, ntpdate and ntptime give all sorts of errors
with the daemon in this condition.
/etc/init.d/ntpd restart shows a fail on shutting down the daemon, but shows
an ok on the start. It will then run for about 5 more minutes, then back to
the dead/locked condition. I have seen this condition on about half of the
machines - and on RH 7.0 and 7.1. On the other machines, NTP is happily
adjusting the clocks with no problems.
Any ideas? (of course, I performed all of the above commands as root.)
