I did some investigations, found SG24-5326-00, which explains that
BPXAS's are WLM server address spaces (fork initiators). WLM maintains a
pool of them to be reused and created when needed. Chapter 5.4 describes
what WLM does when a fork initiator is requested: when one is available
it is resumed and the application continues, when the pool is empty, the
fork request is suspended and WLM creates a new address space and posts
the waiting task.

Can you point me to docs that describe that WLM takes system resources
(besides MAXPROCSYS of course) into consideration to decide whether or
not, or when, to create a new address space?

Next info: sg246472 says in ch. 9.1.3: Note: The creation of these WLM
fork initiators is based solely on demand, not on goal
management.

This implies that each BPXAS request is honoured, if not limited by
MAXPROCSYS.

Kees.
