If you have more than a handful packages(!) selected for 32-bit installation,
this may be the likely explanation.
If you have selected whole categories to install, this is more than likely

Start low, install base package, then add packages that you actually need.
Don't blindly install everything that is available.

(Sorry for being C.O. of the day…)

For "what else", there's always BLODA.
Haven you checked your system for anything potentially heavy-handed?
