As per the documentation, the fork option on pdns-recursor is still in
the experimental stage.

See:

http://downloads.powerdns.com/documentation/html/built-in-recursor.html#RECURSOR-SETTINGS

"fork

    If running on an SMP system with enough memory, this feature forks
PowerDNS so it benefits from two processors. Experimental. Renames
controlsockets, so care is needed to connect to the right one using
rec_control, using --socket-pid."

Therefore, if you are to run it this way, to query the statistics and
stop the processes cleanly, you will need to use the --socket-pid
parameter.
