Memory at 100% LRH Ent 4.0

It's probably not an oversized Oracle SGA if it still appears to use
100% when it's shut down.  Linux caches memory that isn't being used, so
it only looks like it's using 100%.  Cached memory can be reclaimed by
processes that need it.  Can you cat /proc/meminfo and paste its output
here?  Also run top, and sort by memory usage by pushing M, and see if
any of the top processes appear to be using an abnormal amount of
memory.
