It is running a torrent client serving up various linux

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).
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):

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
I think it is fairly safe to say 4.19 + mlx4 + these 4 commits is OK. At
least for my workload. Servers are now 51-61 hours in, no splats. I also
added ntp pool traffic to one of them to make things a little more exciting.
Not sure what is needed for 4.18, I dont have the mental bandwidth to
test that right now. Also no idea about the similar looking mlx5 splats
reported elsewhere.
