I have long discussion with SA. also they are checking all the system
and found that buffer_cache for FS takes the memory that it sould not
to be.

thanks to juan, that he directed me to discuss about dbc kernel parameters.
according to glance, the buiffer it takes 21GB (almost 50% of all
memory). and the swap isn't used by system even when spike loads in
oracle need it much more memory.
