My guess is that it is close to your free memory. If, in the meantime, you want to find out which processes are using swap, you can find them using 'top'. Start top, then press f, followed by p and <Enter>. You should now see an extra field headed 'SWAP'. If you now press 'M', you will order processes by memory usage. Hope this helps.
