My fault: of cause it is *M*. But still, not enough for normal usage.

I bet you find something when you google. I wouldn't want to argue
further. Once you have - let's say - 200 MB free and it fails, I'd be more
tempted to consider the case questionable. It doesn't matter how much RAM
you have (or swap), there must be enough.

What is 'somewhere', except it kills one or another ? 'Freeing up' means
from RAM into swap. But your swap is full as well.
