Another way that I find helpful is to use an IPCS dump and go to option 6 and use
VERBX VSMDATA 'SUMMARY'
Then max down to the bottom. There is summary of the storage layout. This is
a sample. Someplace in your listing will be something that will not look
right. Once you have a subpool and key you can look at the data in the first
part to find what is being allocated too often, or maybe not being released
when it should.
