Often, always, when I run reboot from a Debian 9 container the LXC doesn't reboot, the pct list command doesn't works more and with ps aux | grep "lxc" there are two sessions of the same container.
After kills them the pct list command start to works again, but the container don't starts anymore.

File log attached

Yes, seems very similar, thank you. Now I switched to privileged container, 'cause seems similar problems happens only to my lxc unprivileged.
