Fellow monks, I have a script similar to this one (only much bigger)
use strict;
use warnings;
use English;
use Tk;
use ... # lots more modules

if (fork()) {
  sleep(5);
}
my @out = `myprog`; # produces some output
print @out;

The problem is that this script does not actually execute myprog. If, however, I get rid of many of the modules (basically use less memory), then everything is fine and dandy. So, in other words, this seems to be a memory issue - perl is trying to execute another program, but there is not enought memory to run it. How can I validate that this is the case?

Also, I'm seing this on an Spark Ultra 1. The same program works fine on a Sun Blade 150. However, since myprog is still under development and growing, how can I see how much extra memory I have under that hardware when everything is working?
