[nsd-users] nsd can't bind udp socket: Address already in use

[zongo saiba]

Greetings,

Unbound 1.4.20
OS X 10.8.4 - Server
NSD 3.2.15

I have installed 'unbound' and it works nicely on my client (test 
purpose) - Client is MacBook Air.
I have installed NSD (will be in replacement of BIND) on said client.
All is good but when i try to start NSD

Error --> nsd can't bind udp socket: address already in use.
Everything is configured to bind to 127.0.0.1.
# netstat -anp tcp | grep 127.0.0.1
tcp4       0      0  127.0.0.1.8953         *.* LISTEN
tcp4       0      0  127.0.0.1.53           *.* LISTEN
tcp4       0      0  127.0.0.1.311          *.* LISTEN
tcp4       0      0  127.0.0.1.631          *.* LISTEN

So I understand that 127.0.01 is just booked by other processes and in 
particular unbound.

What troubles me is how to solve that issue ?

Kind Regards,
