Well, on this machine there is no swap space ;)

These are the values for the keys:

$ egrep "ram_max_used_idle_pct|ram_max_used_busy_pct"

It seems a safe situation, but the problem appears anyhow (and I
didn't change those parameters in the meantime). I was on 6.2.12 while
now I'm on 6.2.14 (waiting for .18 to be built for amd64) so I don't
know if in the meantime it was fixed or not.
