Dear Andrew I used latest version of master branch, I will replay the test with debug build to make more debug info ASAP. Vpp is running on Xeon E5-2600 series. I did the tanother tests with two rx-queue and two worker, also with 4 rx-queue and 4 worker, I got segmentation fault on the same function.
I will send more info in few days.
