I vaguely remember discussing this on IRC. IIRC the case was something in the container getting stuck in D state because of a kernel bug. In such case, the container couldn't be killed as anything attempting to do so would get stuck too.
Anyway, this is pretty unfortunate but it's a kernel bug and there's nothing LXC can do to kill an unkillable process so I think our current behaviour is fine and the kernel is what should get fixed. ** Changed in: lxc (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1261338 Title: lxc-stop and even lxc-stop -k can hang To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1261338/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
