I seem to recall that common/shared memory objects are associated with the RASP address space rather than *MASTER*.
There are a non-trivial amount of ISV software products that squirrel stuff away in ASID(1) off existing TCBs and some even go so far as to schedule an IRB over to ASID(1) and create their own TCBs to store stuff. I suggest the customer takes an in-flight dump of ASID(1) and run some IPCS VSMDATA reports - maybe they could narrow the usage down by subpool/key and sniff the storage contents for eye-catchers that might provide clues as to ownership or purpose.

Almost a year ago in https://www.ibm.com/developerworks/community/blogs/MartinPacker/entry/bad_data_and_the_subjunctive_mood?lang=en I talked about seeing large numbers for memory in MSTJCL00. At the time I got no takers as to what it could be. So I'm trying again here... ... Is MSTJCL00 the anchor for something? Common Large Memory Objects perhaps? And are YOU seeing large memory numbers? I ask because I've seen it again in a customer with z/OS R.11.
