Synopsis: /etc/rc.d/nsd stop does not stop nsd
Category: nsd
Environment:
System: OpenBSD 5.6
Details: OpenBSD 5.6-stable (GENERIC.MP) #0: Thu Dec 18 19:01:42 MST
2014
Architecture: OpenBSD.amd64
Machine: amd64
Description:
When running "/etc/rc.d/nsd stop" the nsd daemon does not stop. This also
causes issues with "/etc/rc.d/nsd restart" as nsd is already running since
it didn't stop correctly.

How-To-Repeat:
Have nsd running. Attempt to stop nsd via "/etc/rc.d/nsd stop" or attempt
to restart via "/etc/rc.d/nsd restart".
Fix:
Workaround: kill `cat /var/nsd/run/nsd.pid`
Did not look into rc script for permanent solution.
