I made some tests and find out that for machines whose MAC address is 
used to get a fixed-address DHCP don't write the lease in dhcpd.leases.

If I try with an unknown client, the release and renew of the lease is 
smooth and the "annoying" message is not shown (because named managed to 
delete the record at the release moment):

Now I think I'd better to join dhcpd-user ML and ask why for a machine 
with a fixed-address the lease is not written...
