Hi guys,

Recently had problem with my Sarge firewall box. It just stopped answering to DNS requests from other machines on LAN. When I noticed, I tried to restart named daemon using /etc/init.d/named restart, but it just couldn't stop it. Then I killed this daemon using kill command and started it again. Everything started working again, but on next day I received mail from LogWatch and found there:

Don't really understand what is it all about. Can anyone help me please? Don't want it happen again, it stopped work at office for half a day.

Thank you in advance!
