In my all-in-one devstack setup, I've noticed the following exception in dhcp-agent logs. Basically it implies that dhcp-agent could not find the dhcp tap interface, so its re-creating the dhcp-interface (which is failing for some reason). This operation goes into indefinite loop and we see the above exception from ACLService.
After re-starting the dhcp-agent, the problem disappeared.
