This might indicate that the interface genev_sys_6081 is flickering.
The reason for this might be a problem during creating the GENEVE
tunnels for OVN.

Would you please share the last lines of all files
in /var/log/openvswitch and the relevant lines of /var/log/messages?
If the error is about too many files open, would you please share
the ouput of
ss -lap
lsof
on the affected host might point which files are opened.

The output of
ovs-vsctl list Interface
will show the state of the tunnels.

Can the affected host reach the other OVN hosts via their
remote_ip on udp port 6081?
A check by netcat might give a hint:
ovs-vsctl list Interface | grep remote_ip
nc -zuv <remote_ip> 6081

Does running
systemctl restart ovn-controller
fix the issue?
