+ A change [0] prior to the release of OVN v20.03.0 introduced a change of
behavior where the inactivity probe for the ofctrl connection defaults to 5
seconds. Since this normally is a unix socket the default was not to have a
inactivity probe at all.
On a busy system a inactivity probe of 5 seconds is not enough for the
OVN Controller to complete programming of the switch.
The change of behavior was corrected in [1] and I think it would be
beneficial if Ubuntu backported this fix to the OVN package rather than
having charms and/or end users work around the issue by manually
configuring the timeout through the `external-ids:ovn-openflow-probe-
interval` key in the Open_vSwitch table.
Symptoms of this problem is that a OVN controller is either unable to do
initial programming of a switch for a host with many ports and flows or
that updates are lost on a functional system. The following will be
printed in the log:
2020-10-11T18:56:09.355Z|30186|rconn|ERR|unix:/var/run/openvswitch/br-
int.mgmt: no response to inactivity probe after 5 seconds, disconnecting
