Also, I should mention that the commons-logging / log4j "leak" is because
the shutdown process is not correctly followed. You should have an
application context listener which 'shuts down' the logger when the
application's context is destroyed, i.e.,
public class ApplicationLifecycleListener implements ServletContextListener
{
private final static Log logger =
LogFactory.getLog(ApplicationLifecycleListener.class);
public void contextInitialized(ServletContextEvent sce)
{
logger.info("Application context initialized.");
}
public void contextDestroyed(ServletContextEvent sce)
{
logger.info("Application context destroyed.");
LogFactory.release(Thread.currentThread().getContextClassLoader());
}
}

Subject: Re: Tomcat 5.0.28 memory leak
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.

Have you tried profiling your application?
