I verified is by using the "H" flag to ps like so: without the "H" flag ps ax|grep named 27716 pts/0 Sl 0:00 named -f -g -n 1 27729 pts/0 S+ 0:00 grep named with the "H" flag ps axH|grep named 27716 pts/0 Sl 0:00 named -f -g -n 1 27716 pts/0 Sl 0:00 named -f -g -n 1 27716 pts/0 Sl 0:00 named -f -g -n 1 27716 pts/0 Sl 0:00 named -f -g -n 1 27737 pts/0 S+ 0:00 grep named And named logs how many _worker_ threads it is starting, which always matches the "-n N" input 24-Feb-2011 11:44:33.669 found 2 CPUs, using 1 worker thread 24-Feb-2011 11:44:33.669 using up to 4096 sockets _______________________________________________ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
