What free shows above is quite normal. The kernel will swap out
little/non used process memory in favour of increased buffers and file
cache. This can make your machine more responsive when, for example,
browsing the filesystem, as it won't need to go to disk (so
You actually have over 300MB free memory (the free memory in the second
row is equal to the sum of the free, buffers and cached memory in the
first row). The kernel could make this available very quickly to any
process that needed it, without touching swap.
For example, if you were to open a huge jpeg image your machine would
be able to do so quickly. If you then looked at the output of 'free -m'
you'd find that the buffers and cached used had dropped considerably.
After closing the image and using your machine normally for a while the
memory usage would settle down again to something like it is above.

Are you sure they're not warnings rather than errors?
