is supposed to point out a performance problem, and that is a good thing in my 
opinion, especially when migrating to z/OS 1.8, where the paging/swapping 
algorithm changed drastically. But:

1. The check indicates a medium severity exception. The actual Health checker 
message for this is an information only severity: HZS0004I/ILRH0207I , which 
violates the HC documentation. In addition, this wrong combination is not 
documented anywhere (that I could find), I only know about this because we had 
the 'problem' - just in case this was intended misbehaviour. The message 
combination should be HZS0002E/ILRH0207I. 
2. The check still trips with a high frequency after adding another page data 
set, which is all a sysprog can do. That new page data set is filled first, the 
slot usage of the others doesn't change to get higher, which this check 
completely ignores for the next checking cycle.
3. Given that I want to be alerted when slot usage overall goes higher than 30% 
, I have kept this check, but once it had tripped, I have disabled this check 
via automation for the rest of the IPL (which I do not consider a good thing 
but the lesser of two evils).
