Yo list! I think I'm seeing a problem about bind9.3.1 on FreeBSD 5.3R/AMD64. This is addressed by setting WITHOUT_BIND9_THREADS=3Dtrue when compiling the port. This also doesn't happen on FreeBSD 5.4R/AMD64. The problem manifests when shutting down the named daemon where it just would not die gracefully (you have to kill -9 it). Here are the necessary steps to reproduce it: 1) install FreeBSD5.3R/AMD64 2) install bind9.3.1 from ports (set WITH_PORT_REPLACES_BASE_BIND9) 3) configure a simple resolver (# cd /var/named/etc/namedb && sh make-localhost) 4) start named server ( # /etc/rc.d/named start or # named -u bind -t /var/named ) 5) test some dns queries ( dig, nslookup etc) 6) kill named server ( # /etc/rc.d/named stop or # killall named ),=20 [ this is where it happens ... ] if logging is configured, you'd see something like: 5-May-2005 08:44:32.348 database: debug 1: done free_rbtdb(0.0.127.IN-ADDR.= ARPA) 25-May-2005 08:44:32.348 general: debug 3: zone_shutdown: zone authors.bind/CH: shutting down 25-May-2005 08:44:32.348 general: debug 3: zone_shutdown: zone version.bind/CH: shutting down 25-May-2005 08:44:32.349 client: debug 3: client @0x739400: shutdown 25-May-2005 08:44:32.349 client: debug 3: client @0x739400: free 25-May-2005 08:44:32.349 client: debug 3: client @0x739c00: shutdown 25-May-2005 08:44:32.349 client: debug 3: client @0x739c00: accept failed: operation canceled 25-May-2005 08:44:32.349 client: debug 3: client @0x739c00: free 25-May-2005 08:44:32.349 general: debug 3: clientmgr @0x6feb80: clientmgr_destroy 25-May-2005 08:44:32.349 resolver: debug 3: res 0x73ae00: detach 25-May-2005 08:44:32.349 resolver: debug 3: res 0x73ae00: destroy 25-May-2005 08:44:32.349 general: debug 3: dns_requestmgr_detach: 0x7e1000: eref 0 iref 0 25-May-2005 08:44:32.349 general: debug 3: mgr_destroy 25-May-2005 08:44:32.349 database: debug 1: calling free_rbtdb(.) 25-May-2005 08:44:32.349 database: debug 1: done free_rbtdb(.) 25-May-2005 08:44:32.349 database: debug 1: calling free_rbtdb(.) 25-May-2005 08:44:32.349 database: debug 1: done free_rbtdb(.) 25-May-2005 08:44:32.351 resolver: debug 3: res 0x7e1500: detach 25-May-2005 08:44:32.351 resolver: debug 3: res 0x7e1500: destroy 25-May-2005 08:44:32.351 general: debug 3: dns_requestmgr_detach: 0x7f4700: eref 0 iref 0 25-May-2005 08:44:32.351 general: debug 3: mgr_destroy 25-May-2005 08:44:32.351 database: debug 1: calling free_rbtdb(.) 25-May-2005 08:44:32.351 database: debug 1: done free_rbtdb(.) but then the process is still there: root 31645 0.0 0.1 3580 844 ?? SsJ 4:45AM 0:00.02 /usr/sbin/syslogd -l /var/run/log -l /var/named/var/run/log -ss bind 39312 0.0 0.5 9752 5432 ?? IsJ 8:44AM 0:00.02 /usr/sbin/named -u bind -t /var/named The only way to kill it is kill -9 the pid. Somebody also had some similar issues like this (slapd): http://www.monkey.org/freebsd/archive/freebsd-amd64/200404/msg00076.html w/c is FreeBSD 5.2.X on AMD64. And, as I've said, this doesn't manifest on FreeBSD5.4R/AMD64 nor 5.3/5.4 i386 and the work-around is to compile the port WITHOUT_BIND9_THREADS=3Dtrue, So is anyone else also experiencing this problem? Thanks. cheers mars
