That is the only way you should be stopping and starting NSD.

Debian (and most Linux systems nowadays) run all their processes under
systemd, which supervises them, and ensures that they are restarted in
case they die. If you run "nsd-control stop" then NSD exits without the
knowledge of systemd, and it thinks the daemon crashed, so it restarts it.
