  Sorry. I can say that is a ramdisk formatted to use tmpfs
filesystem! If I need to select one, so can I say that is a tmpfs!

Any files!! Any size!!! From any where!!!  If I´d like to save a .txt
file  ... or download a .tgz file and save in it .. a gif figure to
using later ... just a jpeg ... a HTML file ...   a big movie file ..
a mp3 file ... just a .bin ... or linux module ... download from ftp
... any size ... any file ... from any where!! If I mount a partion on
HD and put things in it  ... consumes memory (RAM) ... and problem
appear!!!
Not important if the file is big or not, if I put things there I had
this problem!!
Suppose that I had 100MB in a partion mounted HD !!!  If I put many
3KB txt in there ... I think that I´ll not problem with memory!!! But
it´s consumes my memory!!!

  No! I umount before it´s stopped!!!  Before memory go 100%  .. And
things back to normal!

  I´ll take a look in it and post here!

   In this case I only use it to see if I had different result! I try
to mount a fat partion too!! Same result!!!
