Dear Janos I already sent an email with the data you requested that is under analysis from your moderators because it is too big. Anyway, every NIC has a number of dropped RX packages but either their number and their daily growth is not big enough to explain the amount of data lost. Further, netstat -su shows, under UDP, 1 packet receive errors only. I'm going to switch UDP devices again to log on not-working NIC (ens35 according data I've sent to you) to verify how many packages are lost in this case and I'll inform you about the results.
