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 ? https://git.kernel.org/pub/scm/linux/kernel/git/davem/net.git/commit/?id=db4f1be3ca9b0ef7330763d07bf4ace83ad6f913No. 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).I'm currently testing 4.19 with the recomended commit added, plus these to sort out some GRO issues (on a hunch, unsure if related): https://git.kernel.org/pub/scm/linux/kernel/git/davem/net.git/commit/?id=a8305bff685252e80b7c60f4f5e7dd2e63e38218 https://git.kernel.org/pub/scm/linux/kernel/git/davem/net.git/commit/?id=992cba7e276d438ac8b0a8c17b147b37c8c286f7 https://git.kernel.org/pub/scm/linux/kernel/git/davem/net.git/commit/?id=ece23711dd956cd5053c9cb03e9fe0668f9c8894 and I *think* it is behaving better now? it's not conclusive as it could take a while to trip in this environment but some of the test servers have not shown anything bad in almost 24h.
Sorry, s/some of the/none of the
