[ntp:questions] minpoll and maxpoll

The daemon doesn't actually crash. What happens is that it sees
the difference as being too large, and it decides that it can't fix
this problem and quits.


Whoever told you that was very, very wrong. Minpoll and maxpoll
have to do with how long ntpd will wait between sending volleys to
the selected time servers, to try and get an idea of what they think
the current time is and how that compares to the others, etc....

If you want to solve this problem, start up ntpd with a "-g"
option, so that ntpd is allowed to step the clock by large amounts
(only on startup). You can help your time server settle down to a
"good" value of time by putting "iburst" at the end of your
configuration lines, and you want to make sure to specify a "drift"
file to record the values that ntpd calculates for how much your
system clock is off from "real"time, which will allow it to settle
back down much faster on restart.


We've tried to address all these issues in the Community

special attention to sections #4 and 5.
