Public bug reported: After deploying openstack on Ubuntu 16.04 on s390x using LXD containers (http://docs.openstack.org/developer/charm-guide/openstack-on-lxd.html) I hit lxc/lxd issues when restarting lxd (or rebooting the host).
Most of lxc commands seem to hang, but a few are returning these errors after few minutes: ubuntu@zfwcec174:~$ sudo lxc list error: Get http://unix.socket/1.0/containers?recursion=1: EOF ubuntu@zfwcec174:~$ lxc info juju-860323-7 error: Get http://unix.socket/1.0/containers/juju-860323-7: EOF This seems to be an intermittend issue, but when this happens I realize at least one forkstart process remains running: root 3409 0.0 0.0 3776 1488 ?
