Hmm, interesting.
I've never come across this one, but also never had to do an OAS install. In this case however, "Those In Command" have decided (against my advice) to combine a DB install and a OAS install in one (virtual) server. Although I'm only doing the DB install, I checked the OAS doco. Apparently it's only an issue for _x86-based_ 64-bit environments, as the 32-bit emulation is only mentioned in the Linux/x86 install guide, not in the one for Linux on zSeries.
Nice to know anyway.

Yep, you're right of course regarding the SwapFree vs. SwapTotal. However, the SwapFree was only marginally smaller (about 50 MB).

Thanks for your thoughts.
