Hello,

I have a FreeBSD 5.4R box running BIND 9.3.1 from base on a dual Xeon
with hyperthreading enabled.

According to the man page for named:

       -n #cpus
              Create #cpus worker threads to take advantage of multiple  CP=
Us.
              If not specified, named will try to determine the number of C=
PUs
              present and create one thread per  CPU.   If  it  is  unable =
 to
              determine  the  number  of  CPUs, a single worker thread will=
 be
              created.

Yet I seem to have six threads:

mx01$ ps -xauwH | grep bind
bind   95906  0.0  5.4 58444 56876  ??  SLs   1:16PM 143:20.01
/usr/sbin/named -u bind -t /var/named
bind   95906  0.0  5.4 58444 56876  ??  SLs   1:16PM 143:20.01
/usr/sbin/named -u bind -t /var/named
bind   95906  0.0  5.4 58444 56876  ??  SLs   1:16PM 143:20.01
/usr/sbin/named -u bind -t /var/named
bind   95906  0.0  5.4 58444 56876  ??  SLs   1:16PM 143:20.01
/usr/sbin/named -u bind -t /var/named
bind   95906  0.0  5.4 58444 56876  ??  SLs   1:16PM 143:20.01
/usr/sbin/named -u bind -t /var/named
bind   95906  0.0  5.4 58444 56876  ??  SLs   1:16PM 143:20.01
/usr/sbin/named -u bind -t /var/named


Does this mean there is a bug in BIND, or am I missing something?

Thanks,
Frem.
