I'm also seeing this problem on 2 of the machines under my control. Two others running bind9 do notpo have this problem. The two that have this problem do have DNSSEC enabled (though only one of them is actually serving a DNSSEC-using zone).
This seems to be related to Debian bug #570852 (http://bugs.debian.org /cgi-bin/bugreport.cgi?bug=570852), which is fixed by the upstream 9.8.1 release, which is included in Precise. I'll try to upgrade one of the affected servers this weekend and see if that fixes it. ** Bug watch added: Debian Bug tracker #570852 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=570852 -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to bind9 in Ubuntu. https://bugs.launchpad.net/bugs/807153 Title: DNSSEC-enabled named sometimes does not die on "service bind9 stop" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bind9/+bug/807153/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
