It might also be the NTP associations - ntpd makes it associations based on
the IP of the local machine, and if your PPP link goes down/up and you get a
new IP then ntpd will continue to attempt to communicate using its old
IP address (association).

In this case one of the better answers is to use linkup and linkdown scripts
that uses ntpdc(?) to tear down the old association (during linkdown) and
brings up a new association during the linkup script.

I have no idea if you can avoid this problem by having ntpd bind to a
(permanent) local address and then use NAT for the periodic connections.

OBTW, if you are using PPP connections for NTP it's probably a good idea to
use both the "burst" and "tinker huffpuff 7200" (more or less) things in
your ntp.conf file.
