Hmmm, ulimit is a sh command, I was using tcsh. The below is after the
advise from Tom Judge to set "kern.maxdsiz="1610612736". I will try from
$ 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
