Peter, Mike: Yes, I remember Peter pointing at Mark's page, but for some
reason I moved on past that to some other line of enquiry.
I've now done what you said, and the results from REXXSTOR in PuTTY are:

V I R T U A L    S T O R A G E    U S A G E
-------------------------------------------
        REGION REQUESTED: 55296K
                LIMIT     IN-USE      AVAIL
BELOW 16M:      8168K         4K      8164K
ABOVE 16M:   2088984K       840K   2088144K

So, the 55296K is that 54M that I've been chasing
and the rest of the report shows that I've been given the maximum amount of
memory possible - 2G, right?

So this whole exercise along with the temporary killing of my z/OS system
*has* been a waste of time.

I'm still left with the two messages though.
And further work by one of the developers shows that the problem occurs
only when BPX_SHAREAS=YES is defined.
Setting BPX_SHAREAS=NO makes the memory problem go away, but run-time
increases significantly.


Thanks for all your support on this problem, Peter - and everyone else who
added their thoughts, too.
(I'm not letting this problem go though - this is one of those times when I
start behaving like a terrier with a rat)

Regards
Sean
