The Unix Return Code in Register 2 will be hex '9C' and the Unix Reason code in Register 3 will be XXXX0012.

The server will have recursive SEC6 abends and various other abends such as U4093, U4036, and S0C1.

Solution:

Increase the MAXPROCUSER parameter in the BPXPRMxx parmlib member and IPL or use the SETOMVS command to increase the MAXPROCUSER.
