On October 12, I updated a whole bunch of packages on my machine to Rawhide versions, including upgrading to bind-9.2.0-0.rc5.1. I've included the list of packages I upgraded below in case any of them are relevant. Before the update, named correctly detected on start-up that I have two CPUs and logged "using 2 CPUs". After the update, it reports "using 1 CPU". Here's what I updated on October 12: 2001-10-12 Jonathan Kamens <jik.ma.us> * Upgraded or installed: GConf ORBit ORBit-devel SysVinit Xconfigurator arts aspell autoconf automake bash bash-doc bind bind-utils binutils bison cpio cracklib cracklib-dicts cyrus-sasl cyrus-sasl-devel cyrus-sasl-md5 dump e2fsprogs eject emacs emacs-X11 emacs-el fam fileutils freetype freetype-devel ftpcopy fvwm2-icons gcc3 gcc3-c++ gdb gettext ghostscript glib2 glib2-devel glibc glibc-common glibc-devel glibc-profile gnome-core gnome-libs gnome-libs-devel groff groff-gxditview groff-perl hdparm imap kdelibs kdelibs-sound ksymoops kudzu kudzu-devel less lha libgcc libgtop libmng libstdc++3 libstdc++3-devel libxml libxml2 libxslt links linuxconf linuxconf-devel magicdev mailcap man-pages mew modutils ncurses ncurses-devel newt openldap openldap-devel openssh openssh-askpass openssh-askpass-gnome openssh-clients openssh-server openssl openssl-devel parted passwd pciutils pciutils-devel pidentd pkgconfig plugger popt portmap procmail python python-devel readline readline-devel rmt samba samba-client samba-common semi sendmail sendmail-cf sendmail-doc setserial sh-utils stat tar timeconfig tix tree ucd-snmp urw-fonts usermode util-linux vnc vnc-doc vnc-server wget xdelta xtraceroute. * Upgraded or installed: rpm, rpmbuild, rpmdb-redhat.
Are you still seeing this with 9.2.0-0.rc7.1? Works here, but might be a machine or kernel specific thing.
Yes, I'm still seeing it: jik:~!52> rpm -q bind bind-9.2.0-0.rc7.1 jik:~!53> grep 'named.*using' /var/log/messages | tail -1 Oct 24 09:37:40 jik named[1035]: using 1 CPU
This is probably fixed in 9.2.0-0.rc8.2 (threading fix). Please reopen if it still doesn't work for you.
