oh okay.. heh sorry:)

what i found out is that by accident when i was removing one domain from my
dns .. i only removed on master ns and didnt remove on slave.. and slave was
trying to connect to master to get this zone.. and somehow bind consider it
as a portscan (weird).. but after i removed this zone from slave those
messages no longer appears..
