Thanks Andrew & Chris Currently testing in 6.0.14 and the memory usage seems a lot more stable (probably a placebo affect). In 6.0.16 both the young/old generation heap usage would increase to 99.xx% and stay there, now both the eden and old heaps are increasing and decreasing. Though the java console lost its connection and refuses to reconnect, but Tomcat is still serving requests and jmap returns values. I'll put that down to a bug in either jconsole or running it on the local machine (never a good idea I know!).

Would it be worth reducing the session timeout? Our app just annotates and returns documents that another server has sent to it. Which rarely takes more than a few seconds each and no more than 2 at a time.
