An IPCS dump will be needed to diagnose this problem,
Use the following command to capture a slip trap of the abend.
where iiii is an arbitrary ID and jjjj is your job name
Also include the full output from the job with the following diagnostic DD's added to the JCL:
//BSTERR DD SYSOUT=* - general error messages
//EN$TROPT DD SYSOUT=* - default options report
//EN$TRST1 DD SYSOUT=* - Storage allocation trace
