This bug needs to be triaged and it needs its acks to be included into the 16.2 zstream So we further debugged this and below are the findings:- When the issue reproduces for a server/port:- - PortBindingUpdateUpEvent is received and put into queue, at this point self.notifications Queue size is large, seen 250+ - The Queue is filled with PortBindingChassisEvent for chassisredirect port in just 2-3 seconds - All the PortBindingChassisEvent is for same port just switching chassis[1], this is just snippet there were total 274 enteries for this particular case, for some cases seen 350+ too. - Same can be seen in ovn-controller log[2], added just snippet and there were in total 134 enteries on one controller and 135 on other. And this resulted into a known old unfixed OVN bug https://bugzilla.redhat.com/show_bug.cgi?id=1974898. So until that is fixed seems we need to revert https://review.opendev.org/c/openstack/networking-ovn/+/823279 which likely causing the issue more often as that switched monitoring to SB DB instead of NB DB, and NB and SB queues are different and NB events will not be impacted with large SB event queue.
