You can't ignore the Spring and Hibernate libraries, which could easily be the cause of the problem. > In the meantime, what's the proper way to increase the > memory allocated to tomcat? Use -XX:MaxPermSize=xx to increase the space reserved for classes. This is only a stopgap, since your memory leak still exists. References for heap and GC management are here: http://java.sun.com/javase/technologies/hotspot/gc/index.jsp Most of that is related to the main Java heap rather than PermGen, so is probably not pertinent to your situation. Use JConsole to find out what's actually going on inside the JVM memory spaces. > And should I allocate more than my physical ram? Definitely not - that will cause page thrashing and kill your performance. > Is there a general formula for how much ram to allocate to > tomcat on a machine dedicated to only that function? No, because Tomcat itself uses very little of the heap; it's pretty much all dependent on the webapp(s) you're running. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
