Hi,

I am seeing these error logs in ovsdb-server.log file:

Here is my environment:
1. OVS from branch-2.12 branch, running in a docker-for-mac. And OVS is
operating in userspace datapath.
2. Faucet controller(tried with ryu with simple_l3 as well, with similar
observation). Controller is in docker as well.

I tried OVS from other release branches(branch-2-11/2.10) as well. Are
there any fine tuning adjustments(to adopt for the docker environment) I
can do to avoid these error messages?

OVS Configuration I have is very simple one:
root at c8e13db3de62:~/ovs# ovs-vsctl show
19665ac0-ba46-4bcf-83b6-ce5b93c23987
    Manager "tcp:172.26.0.2:6653"
    Bridge "br0"
        Controller "tcp:172.26.0.2:6653"
        fail_mode: secure
        Port "br0"
            Interface "br0"
                type: internal
    ovs_version: "2.9.7"

Thanks
