The utility was unable to allocate an output descriptor. rsn is the dynamic output return code (S99ERROR) and info is the information code (S99INFO).
The utility terminates immediately.
A return code of 0x4 and info code of 0x0401 are most likely caused by the utility running in shared address space. Turn off the shared attribute bit using extattr and contact your system programmer to investigate the process used to install the utility. All other codes can be looked up in the dynamic output return codes table found in the z/OS MVS Programming: Authorized Assembler Services Guide . If the problem cannot be resolved, note the return and info codes and contact your system programmer or follow local procedures for reporting a problem to IBM®.
