COBOL for AIX:limit the amount of memory used by CPM loaded modules

Controls the amount of memory used by CPM:

1. limit the number of modules loaded by CPM, By specifying the upper limit of the number of program modules

Or
2. limit the amount of memory used by CPM loaded program module, by specifying the upper limit of the total amount of memory


I found in the test, When the COB_CPM_SIZE_MAX value is set between 64 and 128, the memory used by CPM will expand from 32K to 64K, and then from 64K to 128K with the increase of loading program module. At this time, a total of about 2500 program modules are loaded, the memory used by cicsas is more than 900m, and the memory segments of 0x30000000-0x60000000 are nearly exhausted. According to our experience, cicsas will be coredump when it runs out of 0x30000000-0x60000000. So, how can i limit the number of loading modules to 2000?
