This sounds like an issue with installed services running different versions, rather than a bug. Have you tried asking for support on https://ask.openstack.org/en/questions/ ? You may be able to get help there.

Attempted method: update_service_capabilities Status in neutron: Invalid Bug description: I am confronted with a strange problem... I have OpenStack Mitaka running on Ubuntu 16.04. I have an HA deployment with 2 controllers and 3 compute nodes. I am using OpenSwitch. Everything is working, but after some days I have a network issue on one compute nodes. I am unable to reproduce the problem. But when I try to ping a floating ip that is assigned to a VM on this compute node. I get no reply. I have already verified that all ping requests are received by the tap interface. I have an error in the neutron-openvswitch-agent.log: 2016-06-20 09:38:37.475 16138 ERROR oslo_messaging.rpc.dispatcher [-] Exception during message handling: Endpoint does not support RPC version 2.0.
