Hello£¬i here a issue which i dont know the reasons about it. my "openstack+ovs" system, the ovs-vswitch cpu load is too high, "top -Hp xxxx", the thread revalidator is high, other is not so high. but, the high cpu load will become low after i restart the ovs. i look the log and code, there are this print which i guess the reason lay on.
