In some memory termination environments, such as DAT errors, a task's recovery routines and end-of-task resource managers do not get control. The system gives control only to end-of-memory resource managers. To protect against these situations, a member can have an end-of-memory resource manager routine that runs in the master scheduler address space. This routine can do cleanup for the member, and issue IXCQUIES, IXCLEAVE, and IXCMSGOX for the member.

If the member did not provide an end-of-memory resource manager routine, XCF ensures that the member is disassociated.

If the member is address space associated, I/O for the member is cleaned up before XCF ends the member.
