[lxc-users] lxc stop / lxc reboot hang

[Tomasz Chmielewski]

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


Running these:

Any clues how to fix this?
