In addition to Igor's excellent advice, try the following.

> 3. Used memory has only gone back down to 4GB and is holding at this level

Take a heap dump and find out what's consuming the space.  Look here for some ways to do so:

> 4. The Used physical memory went up from 2GB to 14GB and has stayed there

That may be just allocated but now unused Java heap - but it could also be something outside
of Java that's eating up the memory.  The Java heap is easier to diagnose first, but if that's
not sufficient you may need a C++ heap analyzer, but using one is rather non-trivial with
the JVM.
