Bug Description
It would be useful to have the option to specify inactivity_probe and max_backoff for OVS bridge controllers in neutron config.
OVS documentation says (https:/
The default 5 seconds inactivity_probe value is not sufficient and ovsdb-server drops the client IDL connections for openstack deployments when the neutron server is heavily loaded.
This indeed can happen under the heavy load in neutron-ovs-agent. This was discussed in http://
Alternative is to set this settings manually after each neutron-ovs-agent restart:
ovs-vsctl set Controller br-tun inactivity_
ovs-vsctl set Controller br-int inactivity_
ovs-vsctl set Controller br-ex inactivity_
ovs-vsctl set Controller br-tun max_backoff=5000
ovs-vsctl set Controller br-int max_backoff=5000
ovs-vsctl set Controller br-ex max_backoff=5000
