It is a mistake to give java 6gb out of 8gb available. First, when you
say 6gb, thats just the heap - the java process will use memory beyond
6gb. That doesn't leave you with hardly any RAM for any other process.
And it leaves you almost *nothing* for the filesystem cache.
Effectively, you are starving yourself of memory. Lower the heap by a
lot - start low- giving java more ram than it needs is not beneficial.
So start low and monitor the heap usage using your container, jconsole,
or visualgc. If you don't pin the min and max, you will see how much the
jvm actually wants but what actually gets allocated (start with a low
min for this). Lower your max accordingly.
