[lxc-users] lxc stop / lxc reboot hang

[Tomasz Chmielewski]

Again seeing this issue on one of the servers:

- "lxc stop container" will stop the container but will never exit
- "lxc restart container" will stop the container and will never exit


# dpkg -l|grep lxd
ii  lxd                              2.0.9-0ubuntu1~16.04.2              
amd64        Container hypervisor based on LXC - daemon
ii  lxd-client                       2.0.9-0ubuntu1~16.04.2              
amd64        Container hypervisor based on LXC - client


This gets logged to container log:

             lxc 20170301115514.738 WARN     lxc_commands - 
commands.c:lxc_cmd_rsp_recv:172 - Command get_cgroup failed to receive 
response: Connection reset by peer.


How can it be debugged?
