[Oisf-users] Suricata with PF_RING and IXGBE

[Yasha Zislin]

I understand what you are saying but PF_RING claims that they have fixed this issue (if this is the same problem)
PF_RING-aware LibpcapFixed pcap_brekloop (tcpdump now handles sigterm correctly when there is no traffic)
Also, I have about 400 packets a minute. So you think that just one thread is working and others are idle with no traffic?
