Yesterday i have more than 6 random reboots, and after i set from 3800 to
16000 the min free limit, i have none at this point. :-)

Oh that's good. It's sad that you had random reboots though :(

Anyway, i interested about cache/buffer mechanism, because i have some
performance problems too, and i can see, these systems wastes the half of
memory instead of speeds up the operation.

Yeah, as I said, block device's pagecache (aka buffercache) can't
use highmem. If nbd can export regular files as block devices, or
you use loop devices from regular files, that might help (or slow
things down :P).
