(MVS, VM, and VSE) EREP encountered more than 16 unique CPUs in the input data.
Processing continues.
Code the SYSIMG control statement to reduce the number of CPUs to the actual number of system images. Rerun the job.
If you still have excessive CPUs, you may need to code the CPU or MOD selection parameter in addition to the SYSIMG control statement. This restricts the number of processors whose records are processed.
