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?

Suddenly, today, I'm not able to stop or reboot any of containers:
# lxc stop some-container
Just sits there forever.
In /var/log/lxd/lxd.log, only this single entry shows up:
t=2017-02-03T03:46:20+0000 lvl=info msg="Shutting down container"
creation date=2017-01-19T15:51:21+0000 ephemeral=false timeout=-1s
name=some-container action=shutdown
In /var/log/lxd/some-container/lxc.log, only this one shows up:
lxc 20170203034624.534 WARN lxc_commands -
commands.c:lxc_cmd_rsp_recv:172 - command get_cgroup failed to receive
response
The container actually stops (it's in STOPPED state in "lxc list").
The command just never returns.
