REAS=0B250012,ZA.DM100D.P010.M01.NAMES.S0PA
Check the contents of the REAS= of the message. In the above sample you will see that REAS= has a hex 'XXXX0012' Unix Reason Code.
Search for the meaning of the Unix Reason Code in this IBM document: z/OS UNIX reason codes
Reason Code x'0012' indicates:
JRMaxChild
The maximum number of processes for this user ID has been exceeded.
Action: Ask the system programmer or system administrator to increase the MAXPROCUSER parameter of the BPXPRMxx parmlib member.
Have your Systems Programmer and/or your Security Administrator verify:
a. If the value for MAXPROCUSER needs to be increased in the BPXPRMxx parmlib.
b. The userid in question requires a valid OMVS segment with the proper value for PROCUSER.
Note: The rule of thumb is double your MAXTASK value to get the PROCUSER value.
MAXTASK of 500 in XCOM 11.6 will require a PROCUSER of 1000. For example:
TSS ADD(acid) PROCUSER(1000)
