That is persistent across Suricata restarts, just different thread (usually either thread number 1 or thread number 4).

This is quite odd. There have been no serious changes to af_packet since 2.0.

I'm closing it for now. Restarting latest master did not show this problem. It may be linked to the new synchronized start which has been fixed due to another problem.
