Comment 14 for bug 1304181

Assaf - sorry why doesn't the next resync fix it? We call self.safe_configure_dhcp_for_network() https://github.com/openstack/neutron/blob/stable/icehouse/neutron/agent/dhcp_agent.py#L167 which catches the exception so it can continue syncing. I agree that it sucks that we get in a state where we keep resyncing. I think we might as well backport this patch to avoid this. Though I don't see how this causes a DOS.
