When your boss won't buy you more hardware, and expects you
to do your job anyway, and your job involves deploying
services on the available machinery.

As long as the processing load, when swap is included, doesn't
impact user-visible performance, it probably doesn't matter if
you are swapping or not.

So I'm going to say there's a fair bit of distance between
"user experience broken", "organization broken", and "server
broken", with "server broken" being last in line...  8-).
