As discussed on the mailing list, would you be able to test a modification to the systemd-oomd configuration by placing a new file in /etc and report back if that improves the situation for you (after a reboot)?
$ cat /etc/systemd/system/-.slice.d/10-oomd-root-slice-defaults.conf [Slice] ManagedOOMSwap=auto
