Public bug reported:
This situation always happens when I run high memory consumption applications
like eclipse or virtualbox.
You can repeat this situation by filling memory with some applications, push
your computer to sleep and after waking up it
starts moving memory pages to the swap (probably because that they was not
touched for a long time while sleeping). Please see my top output in
attachment.
