I found that this error occurs when delete old DHCP agent (in "xxx" state).

I check database and found duplicate in table "networkdhcpagentbindings"
like that:
<ID_of_network1> <ID_of_old_DHCP_agent>
<ID_of_network1> <ID_of_new_DHCP_agent>
<ID_of_network2> <ID_of_old_DHCP_agent>
<ID_of_network2> <ID_of_new_DHCP_agent>
v.v...

I manual delete all records relate to <ID_of_old_DHCP_agent>, restart
neutron-server and everything is OK.

Best Regards,
