What do you mean, "caching RAM"? You might mean, caching *IN* RAM, which
would make more sense to me. (Caching RAM seems like it would have a
negative performance effect -- not much of a cache! -- unless your RAM cache
was stored in... well... RAM. ;-)
Second, what leads you to believe that some process is creating a cache on
your server? Are you referring to the display in top which says "358400K
cached"? If so, that is your file cache, which just indicates that you have
free RAM, so Linux automagically used that to store recently accessed files.
(It will be the first RAM freed if a need arises.)
You might also mean that 350MB of your Swap space is being used. If so,
that would indicate to me that some process is using hordes of RAM, which
should be obvious if you run "top" and sort by memory size.
If you mean something else, describe it to us.
TTYL,
