Comment 31 for bug 721896

I don't know what's causing the issue but you're chasing a ghost if you're trying to tune your swap/memory environment.

I don't think so - as I can see, when this happens to me, kernel copies (whats interesting it realy copies, not moving ) content of ram to swap ( without any reason, even when 20% of RAM is free ) untill swap is full.

I have 4G of RAM and 2G of swap
