[Oisf-users] suricata with iptables NFQUEUE and kernel warnings for net/ipv4

[Vieri]

[Follow-up]

I've updated Suricata to v.5.0.2, and this is how I'm running it:

# ps aux | grep suri
suricata 241619 88.0  1.4 3330368 461520 ?      Ssl  10:57   0:04 /usr/bin/suricata --pidfile /run/suricata/suricata.pid -D -c /etc/suricata/suricata-HMAN.yaml -vvvv -q 0 -q 1 -q 2 -q 3 -q 4 -q 5 --set logging.outputs.1.file.filename=/var/log/suricata/suricata.log --user=suricata --group=suricata -l /var/log/suricata

I've also tried running one suricata process for each NFQUEUE, ie. suricata -q 0 [etc.] ; suricata -q 1 [etc.] ; [...] ; suricata -q 5 [etc.], but I'm still seeing these kernel warnings rather often:

Has anyone on this mailing list ever seen these warnings, or does anyone have a clue as to what I could try?

These messages only occur when using NFQUEUE, and after a long time running the system can freeze.
