Yes I tried JProbe and during memory debugging I see char[] size going
up.If I look into bug databases there are various reasons.Some talk to
commons-logging others about session persistance.
I am getting the following error in my log4j log for the application.Also I
noticed if I run tomcat as an application it doesn't break though I do have
memory increase slowly but if I start it as service it breaks even with a
few refreshes of the page.
