Plus this is only on shutdown. Stopping or restarting the script while the machine is in a normal running state does what is expected of it and releases the IP. -- dhclient3 hangs on shutdown https://bugs.launchpad.net/bugs/571933 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dhcp3 in ubuntu. -- 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

[Bug 571933] Re: dhclient3 hangs on shutdown
Went ahead and modified /etc/init.d/networking to provide straces of the ifdown command that is runs on a stop action. running.png is a screen shot of my VM's normal output when running `/etc/init.d/networking stop shutdown.png is a screen shot of the same VM's shutdown logging. running.strace is a strace of the ifdown command that is being initiated by `/etc/init.d/networking stop` when ran while the system is in a normal up condition. shutdown.strace is the same strace but when the ifdown command is ran by `/etc/init.d/networking stop` during the normal shutdown procedures triggered by `/etc/rc6.d/S35networking`. -- dhclient3 hangs on shutdown https://bugs.launchpad.net/bugs/571933 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dhcp3 in ubuntu. -- 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

[Bug 571933] Re: dhclient3 hangs on shutdown
I think my previous two comments really have nothing to do with the actual problem. Me just grasping at straws trying to find some kind of information. The following patch is a hack and not anywhere close to a solution but does make the /etc/init.d/networking script complete during shutdown. ** Patch added: "networking.patch" http://launchpadlibrarian.net/46522420/networking.patch -- dhclient3 hangs on shutdown https://bugs.launchpad.net/bugs/571933 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dhcp3 in ubuntu. -- 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
