If you do use a 32-bit python, then yes, that's the reason. > Appreciate any pointers on how to get my app to be capable of using > the full amount of RAM.

If you are running a 32-bit kernel, then there is *no way* that you could possibly run a 64-bit Python on it. When you do install a 64-bit (i.e. AMD64) version of Ubuntu, it will come with a 64-bit Python executable, so no need to build Python at all. If you still wish to rebuild Python, then, on the 64-bit Ubuntu, the standard configure;make;make install will do the trick. Regards, Martin -- http://mail.python.org/mailman/listinfo/python-list
