I still have 2 ntpd processes running indefinitely after bootup of the system, until I manually issue a "/etc/rc.d/ntpd restart", after which the ntpd runs fine. As a separate test, I tried adjusting my resolv.conf to point to an external name server, and I disabled named at startup, and used the original /etc/rc.d/ntpd. I still got the same problem - 2 ntpd processes running indefinitely. Does anyone know why I'm getting 2 ntpd processes running after bootup (and ntpd fails to adjust the clock as a result)? Any suggested fix would be appreciated.
