Hi Jeff,

   To check the memory limits set by a bash shell use shell command 
"ulimit -a".  For a csh use "limit".  Here's an example on my Mac (no 
memory limit).


$ ulimit -a
core file size        (blocks, -c) 0
data seg size         (kbytes, -d) 6144
file size             (blocks, -f) unlimited
max locked memory     (kbytes, -l) unlimited
max memory size       (kbytes, -m) unlimited
open files                    (-n) 256
pipe size          (512 bytes, -p) 1
stack size            (kbytes, -s) 8192
cpu time             (seconds, -t) unlimited
max user processes            (-u) 100
virtual memory        (kbytes, -v) unlimited
