Thanks. Would this imply it has detected multiple CPUs? I still don't
see any mention of it in my logs.
The below output does indicated that you have five threads. I'm not
sure why your log is not showing the message. Double check the log
configuration and check /var/adm/messages for other messages indicating
a problem.

I noticed that when BIND 9.2.4 on Redhat Linux (Intel x86) starts,
the log records:
dns1 named[28513]: starting BIND 9.2.4 -u named -t /var/named/chroot
dns1 named[28513]: using 2 CPUs
When I start BIND on my Solaris 10 SPARC dual CPU (V210) system
9.4.2-P2,
I don't get the message "using 2 CPUs", but that's what I want. I
The message format changed slightly in BIND 9.4.2-p2, from
bin/named/main.c:
#ifdef ISC_PLATFORM_USETHREADS
if (ns_g_cpus == 0)
ns_g_cpus = ns_g_cpus_detected;
isc_log_write(ns_g_lctx, NS_LOGCATEGORY_GENERAL,
NS_LOGMODULE_SERVER,
ISC_LOG_INFO, "found %u CPU%s, using %u worker thread%s",
ns_g_cpus_detected, ns_g_cpus_detected == 1 ? "" : "s",
ns_g_cpus, ns_g_cpus == 1 ? "" : "s");
#else
ns_g_cpus = 1;
#endif
compiled it with './configure --prefix=/usr/local/bind
--enable-threads'
Take a look at the config.log output to check that threading is
indeed enabled, it should be by default anyhow on Solaris 10 system.
and start it with '/usr/local/bind/sbin/named -n 2 -c /etc/named.conf'.
How do I know it's actually using the two SPARC CPUs?
Use "/usr/bin/ps -Lp `pgrep named`" will show you the number of
light-weight-processes (LWP), threads, running for the named process.
Incidently the '-n' option shouldn't be necessary, named can detect
the number of CPU's on Solaris.
