As it turns out, quite often, after a network outage, I get the following sequence of events: Sep 10 04:54:57 freie dhclient[18447]: bound to 201.82.34.171 -- renewal in 4950 seconds.

Eventually, /var/log/messages fills up. This is not a new problem: I've had it for years, I thought I'd reported it before, but fortunately network outages don't hit very often, and the problem doesn't hit every time there's an outage.
