When you say 200k of free RAM, which figure are you reading? It is normal for Linux to use up all available RAM under normal usage, as it will retain a cache of disk pages. It will throw these away if there is a real need for the RAM. For this reason, free will claim close to 100% memory usage long before it actually hits swap.
