While running a test with a continous VM creation/deletion using an orchestration script with-in cloud environment. In parallel we have some monitoring script calling ovs-appctl dpctl/show stats commands every minute.
During VHU port delete, one of netdev references were not reduced to 0 as show_dpif call has not given-up the reference back or doing bad cleanup. This pending deference preventing VHU deletion sequence, this is found to be one of corner case inside dpctl code which results in leaking up netdev which ultimately results in stale VHU entry. After fixing this problematic cleanup, issue is not seen.
