You need to add a young generation size to the command line (usualy 1/3 to 1/4 the heap size):

... -XX:NewSize=300m -XX:MaxNewSize=300m

Also, I am wondering about your client. If each request creates its own session, you could have a lot of session objects hanging around that will not be gc'ed until they time out.

Also, I recommend charting the gcs (as mentioned in my presentation). This will tell you if there is a memory leak of some kind (such as sessions not timing out).
