> I can't be certain it was getting OOM killed when I allowed the VM 4GB of RAM

Of it's actually getting OOMed (and not backing off by itself), I'm pretty sure that's logged in dmesg. Or earlyoom or systemd-oomd if userspace is in play and getting there first.

Thanks for the tip, I will probably try shrinking it back to 4 to see, as that seems like it should be enough RAM for anybody (:
