Hi Guru,
I noticed that if I use 'systemctl restart openvswitch' with the
ovn-northd service running, I get the following output:

This looks like both the ovn-northd and openvswitch services are
restarting in concert (which is what I'd expect to happen due to the
"Requires=" and "After=" stanzas).
Is there a set of reproduction steps that helps demonstrates the issue?
NOTE: I used 'sudo systemctl start ovn-northd' to start the northd
service. Also note, this behavior seems to happen regardless of
"RuntimeDirectory" setting.
