Issue/Introduction

How to determine what caused the SEC6 abend

 

 

 

Environment

Release: XCOM for z/OS 12.0
Component: xcmvs

Cause

An error occurred during processing of a callable service to z/OS UNIX System Services (z/OS UNIX). The callable service may have been originally issued as a function in a program or as a shell command.     

Resolution

To determine the cause of the SEC6 within XCOM you may want to do the following:

 

1. Check your xcomlog for the following messages:

 

      XCOMM0053E #SUBTASK ABEND SEC6  REASON XXXXXXXX IN MODULE(*********),

                     OFFSET(+XXXXXXXX)                                     

      XCOMM0054I   PSW at entry to ABEND: XXXXXXXX XXXXXXXX             

      XCOMM0054I   Data near PSW: XXXXXXXX XXXXXXXX XXXXXXXX            

      XCOMM0054I   Abending Instr ---------*                            

      XCOMM0054I   Registers at entry to ABEND:                         

      XCOMM0054I     0-3:  XXXXXXXX XXXXXXXX XXXX009C XXXX0012          

      XCOMM0054I     4-7:  XXXXXXXX XXXXXXXX XXXXXXXX XXXXXXXX          

      XCOMM0054I     8-B:  XXXXXXXX XXXXXXXX XXXXXXXX XXXXXXXX          

      XCOMM0054I     C-F:  XXXXXXXX XXXXXXXX XXXXXXXX XXXXXXXX  

 

Note: if you don't find it in your xcomlog check the other logs.

 

2. Check the contents of Register 2 and Register 3. In the above sample you will see that Reg 2 has a hex 'XXXX009C' Unix Return Code and Reg 3 has a hex 'XXXX0012' Unix Reason Code.

 

3. Search for the meaning of the Unix Reason Code in this IBM document: IBM Knowledge Center

 

     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.

 

4. In this case your System Programmer will need to increase the value of MAXPROCUSER to prevent this specific SEC6 abend.
