I'm using these versions on a centos container: ovsdb-server (Open vSwitch) 2.15.2 ovn-nbctl 21.06.0 Open vSwitch Library 2.15.90 DB Schema 5.32.0
Today I see the election timed out too and I should increase ovsdb election timeout too. I saw the commits but I didn't find any related change to my problem. If I use ovn 21.09 with ovsdb 2.16 Is there still any need to increase election timeout and disable the inactivity probe? Also is there any limitation on the number of ACLs that can OVN handle? Thanks.
