What is all the stuff written on my console? Do I need to do something with these? Is there a way to not have go to the console?
This log basically tells you that netmap went down and up. If you didn't do anything like restart ZA, Suricata or bounce the port than this indicates 2 potential problems;
1. Crash
2. Port flap
Are you using ZA or Suricata or something that uses netmap driver?
