Neutron not releasing IP addresses

I'm wondering if anyone has run into this issue before. I am currently using the Havana release of OpenStack, with Neutron GRE/OpenVSwitch networking. Whenever I create a new instance, it pulls two IP addresses (public and private). All this works well. If I terminate the instance, then immediately spin up a new one, it tries to pull the next available IP address (the one used by the previously terminated instance). When the instance is booting, it fails to pull an IP address for either interface. If I restart the neutron-server and neutron-l3-agent, then try creating the instance again, networking works.

Is there some configuration option I am missing in neutron to clear out OVS interfaces on instance termination. I can't seem to find any errors in the log files related to this networking issue. I would greatly appreciate any suggestions.
