Any suggestions please Hi Hari, This is one of the most-reported "problems" by new Linux users and its not a bug at all. Whats happening is the Linux kernel aggressively caching things. It uses your "unused" (that is, unused by user-space processes) RAM as a cache for the file system, etc. In general, its a very efficient way of doing things since its making maximal use of your RAM. So, no worries. Ed -- Edward H.
