We are running a heavily XML-based application on Tomcat 4.0.4 on a dual P4 1.4 GHz box with 4GB of RAM. With 9 users hitting the application continuously, we experience OutOfMemoryErrors after tomcat.exe gets up to around 88MB of usage.
Has anyone else experienced strange happenings with Tomcat on Win2K JDK 1.3.1 under load? We're wondering if the JVM is doing this, if there's something in Tomcat that is causing the memory to continuously creep up and never go down significantly, or if we're just really overlooking something in our application framework that is causing objects to not go out of scope. We haven't experienced this problem like this on other platforms (Linux and OS/400) and IBM is testing this application and not seeing the same kinds of results in WebSphere. I'd appreciate any feedback from other XML users here...we have a go-live date just a few days off and these problems are making my life very difficult. I'd like to at least be able to explain the situation, even if it is our fault. Not knowing is very frustrating. Thanks for your help!
