Dear everyone:
Please help me。
My ovn network running into trouble,this is a 250 client openstack+ovn network,every time I make any change on network ,such as creating a instance,the ovs-dbserver cpu went to 100%,and traffic grows to 1Gb/s, did I meet a BUG?

Here is client INFO:
[root at client deploy]# rpm -qa|grep ovn
openstack-neutron-ovn-metadata-agent-17.0.0-1.el8.noarch
ovn2.13-20.09.0-2.el8.x86_64
ovn2.13-host-20.09.0-2.el8.x86_64

on client and server side CONFIG:
ovs-vsctl set open . external-ids:ovn-encap-ip=10.0.1.10
ovs-vsctl set open . external-ids:ovn-remote=tcp:10.0.1.103:6642,tcp:10.0.1.104:6642,tcp:10.0.1.105:6642
ovs-vsctl set open . external-ids:ovn-encap-type=geneve
ovs-vsctl set open . external-ids:ovn-remote-probe-interval="60000"
ovs-vsctl set open . external-ids:ovn-cms-options=enable-chassis-as-gw

nb show error:
[root@ controller tools]# netstat -pln|grep 6641
