If the TCB that owns the dataspace terminates, the dataspace will be deleted. Some software products assign ownership to TCBs in ASID(0001) to ensure their CADS outlast an unexpected server address space termination - other software products have ASID and/or TCB level resource manager routines to cleanup any pointers or associations with the CADS when the server terminates.

It remains the case that SP231 is not task-owned, is not associated with an address space, is not cleaned up in any way by the system at any time. >If I read correctly dataspaces are associated with address spaces. As with many things, "it depends", in part on what you mean by "associated with". Common Area Data Spaces (CADS) might be thought to be associated with their creating address space but of course are addressable from all. I don't recall if they "go away" when the creating address space goes away; normally they would be created by an address space that is not memtermable (such as *master*).
