Well according to the documentation here, a bind() system call fails
EINVAL - "Invalid argument" - when the socker is already bound to an
address. In other words, something else is probably bound to port 53
on that network interface. And since the name server can't bind to it
- because something else is using that port - it deletes that network
interface from the ones that it listens for DNS requests. It can only
do that on port 53 and if something's already there.....
