NS connecting to itself?

[Aj]

I get a lot of these in my freebsd2 server:

Connection attempt to UDP A.B.C.D:2688 from A.B.C.D:53
Connection attempt to UDP A.B.C.D:4167 from A.B.C.D:53

(yes the IPs are same)

my secondary server does the same:
Connection attempt to UDP A.B.C.D:2479 from E.F.G.H:53

I am using bind8.2. Why does it do this and if its a problem, how do I
fix
it?

Thanks.
