No, this is not normal. Lease times are generally set by the DHCP
server as I understand it. However, you may want to check
/etc/dhclient.conf to be sure something isn't in there. Mine is
completely commented out and that is the default since I never modified
the file.You might want the move /var/lib/dhcp/dhclient.leases to some
other location as dhclient will cache leases to this file per the man
page. It could be picking up erroneous information from it.
I just looked at my logs and I have a DHCPREQUEST entry several times
and repeated at non-obvious intervals. I'm going to wath the box with
Ethereal and see what's going on. Maybe there is a buggy dhcpclient on
the loose?
