What lxc version are you using? My best advice is "upgrade".
Last time I had that problem was:
- when the container doesn't handle sigpwr (e.g. centos container that
is NOT created using download template)
- when using some version of xenial container in the past (probably
due to a bug, which should be fixed now)
