Comment 1 Dumitru Ceara 2021-11-05 17:32:58 UTC 
This is seen with density-heavy ovn-heater tests [0] which simulate ovn-kubernetes topologies with:

GWR1  GWR2  ...  GWR-N
 |     |          |
 |     |          |
 +-----+----------+
       |
   join-switch
       |
       |
  cluster-router
       |
 +-----+----------+
 |     |          |
 |     |          |
SW1   SW2        SW-N

With 5000 load balancers (each with 1 VIP) applied on each and every GWR-X and SW-X.
