OOM in PermGen after several deploy/undeploy

[Piller Sébastien]

Hello everybody, I found some problem with my app, when I deploy it/undeploy it several times under Tomcat (5.5) (Unix and Windows). I copied my app war file in the webapp dir, and when it has been fully deployed, I surf on some pages. After that, I delete that war, wait for the end of undeployment, and did it again. The memory used by tomcat grows on each cycle. I did it about ten times, and after that I got the message below: java.lang.OutOfMemoryError: PermGen space     at java.lang.ClassLoader.defineClass1(Native Method)     at java.lang.ClassLoader.defineClass(Unknown Source)     at java.security.SecureClassLoader.defineClass(Unknown Source)     at org.apache.catalina.loader.WebappClassLoader.findClassInternal(WebappClassLoader.java:1853)     at org.apache.catalina.loader.WebappClassLoader.findClass(WebappClassLoader.java:875)     at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1330)     at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1209)     at java.lang.ClassLoader.loadClassInternal(Unknown Source)     at java.lang.Class.getDeclaredMethods0(Native Method)     at java.lang.Class.privateGetDeclaredMethods(Unknown Source)     at java.lang.Class.getMethod0(Unknown Source)     at java.lang.Class.getMethod0(Unknown Source)     at java.lang.Class.getMethod0(Unknown Source)     at java.lang.Class.getMethod0(Unknown Source)     at java.lang.Class.getMethod0(Unknown Source)     at java.lang.Class.getMethod(Unknown Source)     at org.apache.wicket.util.lang.PropertyResolver.findGetter(PropertyResolver.java:506)     at org.apache.wicket.util.lang.PropertyResolver.getGetAndSetter(PropertyResolver.java:331)     at org.apache.wicket.util.lang.PropertyResolver.getObjectAndGetSetter(PropertyResolver.java:275)     at org.apache.wicket.util.lang.PropertyResolver.getValue(PropertyResolver.java:84)     at org.apache.wicket.model.AbstractPropertyModel.getObject(AbstractPropertyModel.java:113)     at org.apache.wicket.Component.getModelObject(Component.java:1539)     at org.apache.wicket.markup.html.form.AbstractSingleSelectChoice.getModelValue(AbstractSingleSelectChoice.java:140)     at org.apache.wicket.markup.html.form.FormComponent.getValue(FormComponent.java:744)     at org.apache.wicket.markup.html.form.AbstractChoice.onComponentTagBody(AbstractChoice.java:344)     at org.apache.wicket.Component.renderComponent(Component.java:2459)     at org.apache.wicket.MarkupContainer.onRender(MarkupContainer.java:1354)     at org.apache.wicket.Component.render(Component.java:2296)     at org.apache.wicket.MarkupContainer.renderNext(MarkupContainer.java:1240)     at org.apache.wicket.MarkupContainer.renderAll(MarkupContainer.java:1370)     at org.apache.wicket.Page.onRender(Page.java:1446)     at org.apache.wicket.Component.render(Component.java:2296) As you can see, it talks about Wicket, but I don't know if it is really related to it. I tried on Tomcat5.5/Linux too, and the message is not exactly the same, but it stills speak of PermGen. PS: I use Hibernate 3.2.6ga and several other things in my app, like Jasper, JFreeChart and C3P0 . Does anybody know how to avoid this? Or is the Tomcat list a better place for this?
