This is a brand new 65sp4a installation. We had an abend due to an
application automatically using too much memory (we have capped that now).

However, in monitoring the VM pool, we see that the largest segment has
decreased from 130,000,000 to 76,177,400. It looks like this number did
not decrease until we ran the TSATEST process to benchmark our backup
potential speed.

Is this a concern and should we make any manual settings. I have looked
at the TID and have rough ideas of what it means but would like some
other thoughts.

Thanks. Cliff.
