You want to monitor ECSA usage (which you probably already do).
This function is something alike „selective common area data-in-virtual“. It
requires quite some ECSA storage to administer the virtual storage pages shared
between mmap() users. See „MVS Initialization & Tuning Guide - BMXPRMxx“ -
MAXMMAPAREA for details about how much ECSA is used.
