That part is a warning which you receive from the init script, because
killing an nbd-server kills all connections it's serving. It's just a
warning, so don't worry about it if you're not running anything on the
server (you also don't get it if you run 'stop', and it has no influence
on the exit state)

That part should be fairly self-explanatory. Please read the man page if
you don't understand it.
