We hit this problem too. After some investigations i could find at least one cause (it seems to be bind9).
Running the final "ifdown -a --exclude=lo" in /etc/init.d/networking a bit more verbose showed that the call of /etc/network/if-down.d/bind9 does not return. The script just calls "rndc reconfig". The problem is that the named is not running at this moment any longer because it was stopped before. If i call "rndc -V reconfig" without a running named i see this -----------> snip <------------ create memory context create socket manager create task manager create task create logging context setting log tag creating log channel enabling log channel create parser get key decode base64 secret reconfig post event using server 127.0.0.1 (127.0.0.1#953) create socket bind socket connect -----------> snip <------------ So it seems that the connect does not return. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1010045 Title: 12.04 hangs on shutdown deconfiguring network interfaces To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/1010045/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
