        There is no problem with LVS 0.9.7. Used memory near 100%
is normal. The free memory is in "buffers" and in "cached" too.

        Anyone can try to create small program that reports how
many MB can be allocated. Try with small values first without
touching the swap. This is simple test that can clear the problem.
