Hello folks,
    Here is the problem I encountered, I created a network with subnet that disabled DHCP, there are two IP addresses which are available in the pool, is reserved for the gateway, was allocated to VM. there is no error happened when I update the subnet with enabled DHCP through the dashboard, Actually, the dhcp agent didn't create a corresponding namespace because of "No more IP addresses available", This cause inconsistency between the front and backend. I'd like to know why dhcp_agent does not transfer this exception to neutron_server, then report to the dashboard?  Any help would be appreciated.
