I've tried several variants of 0 <= WRITE_PAD <= 1 on FreeBSD, none with
a reproducible result.
Also I completely fail to understand why this is needed at all, it must
be a workaround for some bug, where ever that is.

I've seen similar things, changes in the order of messages or parts of
the message.

Gary gave FreeBSd a try yesterday and was not able to get a single
failure. No idea on which hardware, but I'd assume on some fast desktop
machine.


So I guess BSD and a slow machine is necessary.

By gitlab-runner is running in a kvm instance on a not-so-recent server
hardware with various VMs, so speed depends on the work the other VMs do..

I think I can get some slow and old firewall hardware and run it in the
datacenter and give people access to it - if the issue is reproducible.
I'll figure it out after Christmas.
