In my deployment, on each Neutron server, there are 13 Neutron server processes. I see 12 of them (monitor, maintenance, RPC, API) connect to both ovn-nb-db and ovn-sb-db. With 3 Neutron server nodes, that's 36 OVSDB clients. Is so many clients OK?
Any suggestions how to figure out which side doesn't respond the probe, if it's bi-directional? I don't see any activities from logging, other than connect/drop and reconnect... BTW, please let me know if this is not the right place to discuss Neutron OVN ML2 driver. Thanks!
