The kernel will use up all available RAM over time as efficiently as
possible so seeing a system using the majority of its memory isn't
necessarily something to worry about.

"Linux tries to use all the memory for disk buffers and cache. It
helps the system to run faster because disk information is already in
memory and Linux doesn't have to read it from disk again. If space is
needed by a program or application like Oracle, Linux will make the
space available immediately. So if your system runs for a while, you
will usually see a small number for "free" in the first line, and
there is nothing to be worried about."
