DHCPD kérdés, lease time ?

Sziasztok,
következőbe kérném a segítségetek...
Felhúztam egy kis gépet routernek, ubuntu

(Linux Sammy 2.6.35-24-generic #42-Ubuntu SMP Thu Dec 2 02:41:37 UTC 2010 x86_64 GNU/Linux)

két IF, egy eth0 és egy wlan0. wlan0 a belső háló, hostapd, dhcp3d configgal megy, a net meg iptables-en keresztül. Minden szép és jó, egyetlen bajom van, a következő sorok szerintem túl gyakran jönnek a syslogba: (kozmetikáztam :)
