http://issues.apache.org/bugzilla/show_bug.cgi?id=29274 WebAppClassLoader does not release loaded classes if webapp is reloaded Summary: WebAppClassLoader does not release loaded classes if webapp is reloaded Product: Tomcat 5 Version: 5.0.19 Platform: PC OS/Version: Linux Status: NEW Severity: Normal Priority: Other Component: Catalina AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] If a wepapp is reloaded using the Tomcat manager, memory occupied by reference type static members from the webapp's classes is not released. Memory is only released if the webapp is undeployed. I guess this is a problem of the WebAppClassLoader. A class itself is only unloaded by the JVM if it's classloader was finalized. If after a reload from the manager the webapp still uses the same classloader, old classes will not get unloaded and so their memory will never be freed resulting in OutOfMemoryError`s. Sample code: class SomeServlet extends HttpServlet { static byte[] bigData = new byte[50000000]; protected void service(HttpServletRequest arg0, HttpServletResponse arg1) throws ServletException, IOException { } } --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
