According to <http://www.redhat.com/en_us/USA/rhel/details/limits/>,
RHEL3's max memory on i386 and x86_64 is 64GB. On x86_64, I don't know of
anything limiting a process to using as much of that as it can get (that
doesn't mean that there isn't a limit, but I don't know that there is).
On i386, of course, you'll get only ~4GB/process.
And if you're running x86_64, I'd strongly recommend centos 4 (which has
the same limits).
