Fair enough - I've seen it more commonly in smaller machines, but they're also more common in the fleets I've observed (and the ones that are more likely to run close to the edge memory-wise). I have also seen it in systems up to 32GB RAM, so it's by no means a non-issue in systems that are at least somewhat larger. The general observation that oomd/earlyoom + swap is a better solution than no swap still generally applies.
