Thank you very much for your reply.
The problem is not easy to reproduce, we have to wait a random long time to see
if the issue happens again. It can be more than one day or longer.
OVS 2.17 with dpdk 20.11 had run to core before, so it's hard to say
if it is related to DPDK.
I'm running the ovs without offload to see if the issue can happen in
recent days.
And again, TLDR, paste more thread call stacks.
Most of the threads are in the state of sched_yield, nanosleep,
epoll_wait and poll.
The following threads are in working state. So hope this can have
clues for investigation.
