Christian,

Sorry for taking so long to get back to you.

We see this in the OpenStack charming team with openstack-dashboard (horizon) and keystone (when run on apache2 >= liberty). We have had to implement hacky work-arounds because apache2 is not waiting until it releases the port(s) before exiting.

You can deploy either of these and then test my loop from above.
  juju deploy openstack-dashboard

The 1428796 is similar in that apache2 is not waiting till it releases ports, but we see this on trusty and xenial so it is not systemd specific.
