I'm finally back to investigate on this bug...

(DHCP issue we investigated)
There was about 215 ports on this hypervisor before tests. Now it is 315. Setup
used: L3 (completely routed setup, no massive ARP at all). This bug back again
at about 250-280 ports binded to the single chassis (x4 chassis in total). I've
also migrated to 100% routed setup with BGP (even hypervisor IP is announced
via BGP to the core).
Once ovs starts to drop ARP (which is still used to find a GW mac) then
instance connectivity goes down.
At this moment I have ovn-controller that contains patch by @dceara which helps
to process DHCP, but unfortunately ovs still break connectivity for unknown
reason.

Seeing next tcpdump inside the instance. It tries to learn GW arp (which is

As you can see trafic flows into VM because of L3 routed setup, however VM
unable to send outgoing traffic because of GW MAC is unknown due to dropped ARP
flows.
