Hi managers,

I had a problem very similar to this one:

http://www.ornl.gov/its/archives/mailing-lists/alpha-osf-managers/1998/02/m
sg00593.html

The problem was a fortran program, wich had the famous:
/sbin/loader: Fatal Error:set_program_attributes failed to set
heap start

Anyway, I solved it just by browsing the list archive...

Now I'm just curious about the solution I found. I can run the fortran
program, if I execute the command:

$ ulimit -d 1048576

Why? What's the ulimit goal?
Why do I have to set it?

This is just a knowledge question. It's not crucial for me.
If you have some time, I would apreciate a reply.
If you don't have time, never mind... Everything is working! :)

Cheers,
