I am getting these messsages on my machine right now, too.

             total       used       free     shared    buffers     cached
Mem:      16386788   15157252    1229536     761064      88852    2660664

Swap:     25165820        156   25165664

There is enough RAM left to allocate a 2 MiB block.
