I am running GMT on a FreeBSD i386 with 2GB physical memory and 6GB total
swap space. Queries to the system show that I am truly running with that
amount of memory (sysctl hw.physmem and top to see swap space.) My GMT
script bombs when the grdproject program tries to allocate less than 100MB
I think I'm on the right track with trying to increase the dat seg size
with ulimit. But even as root, I cannot increase the size of the data
segment above 262144 kbytes.
$ ulimit -a
cpu time (seconds, -t) unlimited
file size (512-blocks, -f) unlimited
data seg size
