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?
