[Bug 1261338] Re: lxc-stop and even lxc-stop -k can hang
Thanks for the information. Indeed, lxc-stop -k still works by talking to the lxc monitor. What appears to have happened here is that the monitor itself is frozen. Could you please show full output of: ps -ef Then do 'ps -ef | grep lxc-start' to find the lxc-start process for the hung container. In one terminal do sudo strace -f -odebug.out -p $pid where $pid is the process id of the lxc-start. Then in another terminal again do lxc-stop -n $container -k and attach the file debug.out to this report. ** Changed in: lxc (Ubuntu) Status: Invalid = Incomplete -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to lxc in 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-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 1261338] Re: lxc-stop and even lxc-stop -k can hang
Sorry for not providing timely feedback there (nor a reproducing env). Truth is this hasn't recur so marking invalid seems fair. Thanks for the help nevertheless, if it happens again, I'll make sure to have such a reproducing env before re-opening this bug. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to lxc in 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-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 1261338] Re: lxc-stop and even lxc-stop -k can hang
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 Server Team, which is subscribed to lxc in 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-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 1261338] Re: lxc-stop and even lxc-stop -k can hang
What exactly is the kernel crash being triggered on the host? What does 'sudo strace -f lxc-stop -k -n container' show? What does the file outout show after running 'sudo lxc-stop -l info -o outout -n container' ? -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to lxc in 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-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
