Comment 7 for bug 1909004

Thanks @Alex

I have discovered something. I wonder this might actually end up being an OVN issue? I found these logs in the ovn-controller.log on the unit, and have noticed similar logs on compute chassis previously. Restarting OVN clears it and has done so in this case too;
