FYI, the system in question had about 175GB of page space - 22 mod 9s.
Currently the system does NO paging. All the guests fit within real
storage. (Of course there will eventually be more guests on that LPAR,
so sooner or later we'll start to page.)

And I think Lee has not yet mentioned how much paging space he had
allocated. With a 175G LPAR you would think he has at least 175G worth
of virtual machines, so 350G of paging space... for the moment the
next virtual machine went over the edge. I very much doubt he was that
well prepared. With that amount of space, things might have gotten
slow but there's a fair chance CP would have survived the abuse.
