Hi,
  When you saw those total/used/free values, what was your swap size?
I.e. what does 'top' give for memory usage stats when the machine
is unresponsive as you're describing. It is quite possible that the
"free" memory is only due to large amounts of swap being used... :)

I wonder is it means that the memory is not enough, and if I should add more memory. The values are 513232/483840/29392 for total/used/free memory on my linux computer.
