AVZ3718E TSO ADDRESS SPACE CREATION FAILED, RC = rcode, REASON CODE = rsncode
Explanation
A failure occurred in the service routine that schedules an address space CREATE. The TSO address space will not be created. The return and reason codes in the message are from the MVS™ ASCRE service routine.
User response
Check the return code in the message. If the return code is 52 or higher, this error is most likely a system related problem, and you should report this to your system programming staff. If necessary, set the TSOSRVUSEASCRE to NO so that START commands (rather than ASCRE) will be used to create TSO outboard server address spaces.
