The below is after the advise from Tom Judge to set "kern.maxdsiz="1610612736". I will try from here, thanks. $ ulimit -a cpu time (seconds, -t) unlimited file size (512-blocks, -f) unlimited data seg size (kbytes, -d) 1572864 stack size (kbytes, -s) 65536 core file size (512-blocks, -c) unlimited max memory size (kbytes, -m) unlimited locked memory (kbytes, -l) unlimited max user processes (-u) 5547 open files (-n) 11095 virtual mem size (kbytes, -v) unlimited sbsize (bytes, -b) unlimited
