Public bug reported:
On an openstack HA kilo deployment using charms trunks,
several services failing to properly restart haproxy, leaving
old instances running, showing cinder/0 as example:
$ juju ssh cinder/0 'pgrep -f haproxy | xargs ps -o pid,ppid,lstart,cmd -p;
egrep St.*ing.haproxy /var/log/juju/unit-cinder-0.log'

As shown above, new haproxy instances ~correlate with
Starting/Stopping lines at juju log, as expected.
FYI same issue find for (HA) services using haproxy, positively confirmed on:
nova-cloud-controller, keystone, glance, cinder,
openstack-dashboard, swift-proxy, ceilometer
