Great, I think that's the cause of the limit you are seeing..

              Memory  specifications in job requests apply to real memory size
              (also known as resident set size). It  is  possible  to  enforce
              virtual  memory  limits  for both jobs and job steps by limiting
              their virtual memory to some percentage  of  their  real  memory
              allocation. The VSizeFactor parameter specifies the job's or job
              step's virtual memory limit as a percentage of its  real  memory
              limit.  For  example,  if a job's real memory limit is 500MB and
              VSizeFactor is set to 101 then the job will  be  killed  if  its
              real  memory  exceeds  500MB or its virtual memory exceeds 505MB
              (101 percent of the real memory limit).  The default value is 0,
              which  disables enforcement of virtual memory limits.  The value
              may not exceed 65533 percent.

Setting it to 0 should make that limit go away.

All the best,
