High Memory issue, any help?

I've recently noticed huge drops in FPS/Lag in certain areas of the game. So I tried trouble shooting online and noticed on the graph my memory is high compared to others and even my friends. It never moves from that number and is persistent throughout the entire game.

Any ideas?
