Dear Andrew, I've already tested your patch and the my observed behavior in last tests exists yet. However in vpp1804, mentioned delete process starts when the session table is full but in master with your patch, process of deleting sessions starts while session table is not full. if it is possible for you, I appreciate you double check. The trex and vpp configs attached in my previous emails.
