Bug Description
On both xenial and zesty apache and haproxy seem to be able to bind to the same port:
# netstat -peanut | grep 8776
tcp 0 0 0.0.0.0:8776 0.0.0.0:* LISTEN 0 76856 26190/haproxy
tcp6 0 0 :::8776 :::* LISTEN 0 76749 26254/apache2
tcp6 0 0 :::8776 :::* LISTEN 0 76857 26190/haproxy
I thought this should not be possible?
