This makes /var/log/messages grow so fast that it could fill entire /var before newsyslog kicks in and cause all kind of problems requiring manual intervention. Lack of Internet, even for extended period of time, shouldn't have such dramatic consequences. I'm therefore marking this bug as critical. I'm using 6to4 for IPv6, my named.conf is derived from default config (added local zones and forwarding to dns servers of my isp). >How-To-Repeat: 1. Disconnect from Internet 2. Restart named or try to lookup anything 3. Watch the logs or console >Fix: >Release-Note: >Audit-Trail: >Unformatted:
