amounts of data. I figured out that a 32 bit application on HP-UX cannot address more than 1 GB of memory. In fact (I think due to the overhead of memory management done by python) a python application cannot use much more than 500 MB of "real" data. For this reason
I don't thik this is likely. Don't know about HP-UX but on some platforms, FreeBSD for example, there is a soft memory-cap for applications. By default, a single application on FreeBSD cannot use more than 512MB of memory, period. The limit can be modified by root (probably involves rebooting).
