Hi Anthony,
the presentation you mentioned in your post is one of the sources of
information we already know. Based on these information we already took a dump
of the RASP address space and run the IPCS commands mentioned there.
Here you'll find an extract of the results. But I couldn't find any special
data there. Even more the number of auxiliary pages named in the report (3,394
+ 10,723 = 14,177) are much lower than the number of pages reported in the
SLOTCNT report. So our idea is that there are some kind of orphaned pages,
which are not released until the next IPL.

But the question still is, if that's true who requested these slots, and how to
avoid this behaviour.
