You need to provide more detail about which octave version you're using, 
which OS, and what kind of hardware. However, based on your description, 
I'm going to make a guess. The only time I ever saw this behavior was on 
the 2.1.73 version on cygwin, when using dynamically loaded functions. 
In this case, there is apparently a memory leak that consumes a few 
bytes of memory for every function call. In a script that runs for hours 
and calls such functions millions of times, this can eventually consume 
all of a computer's resources. I think this is a known problem, but it 
was never clear how to fix it because it's only on cygwin, which implies 
that it could very well be a compiler or cygwin bug. If my guess is 
correct, I would suggest trying the 2.9.12 binary that has been 
discussed on this list recently.
