Comment 22 for bug 501715

I am experiencing the same problem as Petar, after several hours the swap file starts to get heavily used despite free showing less than half my memory being used by applications and having vm.swappiness=0. I have 2G of RAM and 2.5G of swap, and the system behaves normally up until the swap partition starts to get used at which point the system becomes almost unusable. Attempting sudo swapoff -a fails for me as well.
