In the near term, we could consider tweaking the systemd-oomd defaults in Ubuntu. According to the commit that added systemd-oomd in Jammy [1], the current config is based on Fedora's. This includes using the default value of SwapUsedLimit=90% [2]. However, Fedora has more swap space by default: a fresh install of Fedora 35 in a VM with 4GB of memory has 4GB of swap, whereas a fresh install of Jammy in a VM with 4GB of memory has 968MB of swap. So, maybe the default SwapUsedLimit is not appropriate for Ubuntu.
