Seems to be a linux 64 bit thing, but may not be applicable to your situation. It's in the application server installation guide (maybe not for DB installations)...

Always use 32-bit shell emulation, use the following command before running the installer and any other Oracle Application Server commands or scripts:
# linux32 bash

By the way: you should check SwapFree, not SwapTotal. Looks like the installer did not empty your swapspace.
