Summary: dhclient unable to retrieve configuration after several
hours' downtime, rl interface, OpenBSD 4.4-stable
A few days back the ADSL connection to a machine I'm sometimes called
upon to nurture went down for some hours, and when it came back up, it
looks to me like dhclient for whatever reason got stuck trying to ask
for a new IP address. The machine runs OpenBSD 4.4-stable (dmesg at
the end here) and possibly complicating the picture, it's also
configured with no-ip.
here's the time when the line went down,

After a reboot, the problem of course went away. Has anybody here
seen anything similar? Or even better, is it a known problem with a
possible workaround?
Cheers,
Peter
