conf.d and init.d scripts require admin to manually set the number of CPUs available. It would be better to allow bind to autodetect the correct value by skipping the "-n $CPU" option.
Created attachment 199552 [details, diff] /etc/init.d/named patch this patch removes use of "-n" option when CPU is not defined
Created attachment 199553 [details, diff] /etc/conf.d/named patch thich patch changes conf.d/named not to use CPU by default and provides comment about autodetection for bind admins.
Fixed for 9.6.1-r1 thanks for report and patch.
