General thoughts with no hard data behind them. I.E. SWAGs
1) MSTJCL00 (i.e. *MASTER*) has been flagged by WLM as Storage Critical. Check
w/WLM development.
2) Turn on the VSM* parameters in SYS1.PARMLIB(DIAG*) for data gathering. View
w/IPCS and/or RMF.
Not sure what (if any) RSM* parameters are available.
I believe your theory about MSTJCL00 being used as an anchor is reasonable,
however, 2 GB of anchors seems excessive, even in a very large system.
I do not believe this is a backing for anything that does not belong to a
"system address space".
FWIW,

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?
