Comment 10 for bug 1776381

I tried the following on a s390x LPAR instance with Bionic 4.15 kernel:
$ sudo lxc-create -t /usr/share/lxc/templates/lxc-busybox -n test
$ sudo lxc-ls
test
$ sudo lxc-start test
$ sudo lxc-attach test
# Make sure the container is running here

# Use another terminal on this instance to do lxc-stop
$ sudo lxc-stop test
lxc-stop: test: commands_utils.c: lxc_cmd_sock_rcv_state: 70 Resource temporarily unavailable - Failed to receive message
$ echo $?
0

The container terminated.
