What amount of Ram have you got in your system?

Half a gig of RAM and a quarter of gig of swap space.

Are you running many resource intensive apps at the same time as the script (Like any java apps)?

No, the system is mostly idle. No java running. Just Netscape (approx 66 Mb) and X (about 100 Mb), and a few xterms running bash.

I considered system resources, but it doesn't add up. Where the program runs out of memory is repeatable; it only does with 'map', and it doesn't run out of memory if you increase $MAX. That doesn't seem to be consistent with running out of system resources.

The system is Redhat 7.3, running perl 5.8.2. Ah, I see I have 5.8.0 and 5.8.1 installed as well. It runs out of memory with 5.8.1 as well, but not with 5.8.0. Now, that's interesting.
