Hi all, I have a problem running bind on C5.4 when the messagebus service is activated. When I switch off the dbus message service bind runs well. With dbus activated bind crashes with a segfault. How can I get rid of this error? What shall I change? SElinux (the source of most unexpedted things) is switched off. Following versions are installed: bind-9.3.6-4.P1.el5 bind-libs-9.3.6-4.P1.el5 dbus-1.1.2-12.el5 Thanks, Brian. starting the bind causes following error: [root@t41 ~]# /usr/sbin/named -u named -D -t /var/named/chroot -g 04-Nov-2009 16:58:14.905 starting BIND 9.3.6-P1-RedHat-9.3.6-4.P1.el5 -u named - D -t /var/named/chroot -g 04-Nov-2009 16:58:14.906 adjusted limit on open files from 1024 to 1048576 04-Nov-2009 16:58:14.907 found 1 CPU, using 1 worker thread 04-Nov-2009 16:58:14.907 using up to 4096 sockets 04-Nov-2009 16:58:14.943 loading configuration from '/etc/named.conf' 04-Nov-2009 16:58:14.956 using default UDP/IPv4 port range: [1024, 65535] 04-Nov-2009 16:58:14.962 using default UDP/IPv6 port range: [1024, 65535] 04-Nov-2009 16:58:14.978 listening on IPv4 interface lo, 127.0.0.1#53 04-Nov-2009 16:58:14.985 /etc/named.conf:58: using specific query-source port su ppresses port randomization and can be insecure. 04-Nov-2009 16:58:14.990 command channel listening on 127.0.0.1#953 04-Nov-2009 16:58:14.997 ignoring config file logging statement due to -g option 04-Nov-2009 16:58:15.005 zone 0.in-addr.arpa/IN: loaded serial 42 04-Nov-2009 16:58:15.008 zone 0.0.127.in-addr.arpa/IN: loaded serial 1997022700 04-Nov-2009 16:58:15.010 zone 255.in-addr.arpa/IN: loaded serial 42 04-Nov-2009 16:58:15.018 zone 0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0. 0.0.0.0.0.0.ip6.arpa/IN: loaded serial 1997022700 04-Nov-2009 16:58:15.023 zone localdomain/IN: loaded serial 42 04-Nov-2009 16:58:15.026 zone localhost/IN: loaded serial 42 process 13548: arguments to dbus_connection_unref() were incorrect, assertion "c onnection->generation == _dbus_current_generation" failed in file dbus-connectio n.c line 2615.
