Greetings everyone, I was testing DNSSec resolution on BIND 9.8.1-P1 by adding the following options: options { ... dnssec-enable yes; dnssec-validation auto; ... }; Unfortunately immediately after named is restarted one CPU reaches 100% utilization. CPU: 30.1% user, 0.0% nice, 23.6% system, 0.0% interrupt, 46.3% idle Mem: 111M Active, 14M Inact, 255M Wired, 852K Cache, 3558M Free Swap: 2048M Total, 2048M Free PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND 2178 bind 5 20 0 51364K 13828K kqread 0 0:17 84.18% named The system is running GENERIC kernel, and it not an authoritative DNS. Mainly used for testing purposes. My logs don't show anything strange: Jan 5 02:03:55 hp named[2178]: starting BIND 9.8.1-P1 -t /var/named -u bind Jan 5 02:03:55 hp named[2178]: built with '--prefix=/usr' '--infodir=/usr/share/info' '--mandir=/usr/share/man' '--enable-threads' '--enable-getifaddrs' '--disable-linux-caps' '--with-openssl=/usr' '--with-randomdev=/dev/random' '--without-idn' '--without-libxml2' Jan 5 02:03:55 hp named[2178]: using built-in root key for view _default Jan 5 02:03:55 hp named[2178]: command channel listening on 127.0.0.1#953 Jan 5 02:03:55 hp named[2178]: command channel listening on ::1#953 an 5 02:03:55 hp named[2178]: running Anybody has come across a similar behavior ?
