Handler occurs Unreasonable long time over 2s

Hi OvS.

I using OvS and OVN for OpenStack network solutions. But recently, at 00:10 I found that a vm ping others has high delay over 2s. So I dispaly table flows try to find some the issue point, In internal table, the second flow has very high hits. But I dont known why?

And OvN as OvS local controller for br-int with openflow1.5 version, so the the packets cannot send to OVN as we known. A issue case is I have a crond task at 00:10 every day to backup flows for br-int bridge.

So someone can help me answer, why the packets send to controller when I dump-flows by ofctl cli.

我是ovs-dpdk环境，遇到类似的问题
是在删除大内存虚拟机的过程中，删除该虚机的ovs port，就会触发vswitchd hang
