I tried both with SIGTERM and -K, which looked like
/home/aolserver/bin/nsd -s bf2 -Kt /home/aolserver/sfr.tcl -u nsadmin -g web
this is exactly the line I use in inittab to run it except w/o the -i, and with the K, which I assume is the correct way to use that. running same version of nsd as you. I tried running with debug=true and didn't see anything besides the usual
nssock: triggering shutdown
stuff.
