I think that's not due to wrong server, rather to just plain loss of
connection. Still, once it "gives up" I wonder if it every tries again.
Doesn't seem so from the logs. Network connections do go down once in a
That machine is running DNSmasq which is setup to read
/etc/ppp/resolve.conf and detect any changes (I don't think the DNS
machines changes, though). The machine emails me with its IP and DNS
config every time ppp comes up, which is how I know where to find the
machine when its IP changes.

It would be nice if it logged that event. Still, it's hard to imagine that
it would be off line long enough to get that far behind.
I wonder if running hwclock --systohc from cron would fix the problem. It
may be that the machine is being restarted without a proper shutdown (and
hwclock save), so that on restart it's reading a very slow hwclock.
Thanks for the help,
