Some CA IDMS COBOL programs have multiple copies loaded concurrently in the same program pool .
What can cause this?

This can happen when CA IDMS COBOL programs are defined as QUASIREENTRANT. This is the default for COBOL but should only used for old VS COBOL programs which are not LE compliant. This causes a separate copy of the program to be loaded for each task when running multitasking.
For COBOL LE compliant programs they should be defined as REENTRANT so only one copy of the program will be loaded.
Change the programs definition in the SYSGEN to be defined as REENTRANT.
