Thanks, looks like message about too many open files is valid.
Next question is why the geneve tunnel is failing.
Would you share the output of
ovs-vsctl list Interface
?

Can the affected host can 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
