It eventually showed up again with mlx4, on 4.18.16 + fix and also on
4.19. I still do not have a useful packet capture.
It is running a torrent client serving up various linux distributions.
Have you also applied this fix ?

No. I've applied it now to 4.19 and will report back if anything shows up.
Just hit it on the simpler server; no VRF, no tunnels, no nat/conntrack.
Only a basic stateless nftables ruleset and a vlan netdev (unlikely to
be the one triggering this I guess; it has only v4 traffic).
On 4.19 + above commit:
