- Glassfish Server up vote 27 down vote favorite 14 I am running java web application using Hibernate and glassfish Server. I am getting java.lang.OutOfMemoryError: PermGen space exception when after I deploying it several times.

Each time you redeploy the application, a new classloader is created for it and all classes of your application are loaded again. This consumes memory in the perm gen space. The old classloader and all its loaded classes have to be garbage collected, otherwise you will eventually run into a PermGen space OOME after deploying multiple times. This does not work if an object loaded by an outside classloader holds a reference to any object loaded by the old classloader. This article gives a good explanation of the problem. Generally, classloader leaks are difficult to analyze and sometimes difficult to fix. To find out why the old classloaders are not garbage collected, you have to use a profiler. In JProfiler, use the heap walker, select the glassfish classloader objects and use the incoming references view to check for paths to garbage collector roots. The class loader class is called org.apa

This is related to the memory options in the domain.xml file. We increased the -Xmx and -Xms jvm-options settings to 1024 instead of the default 512, like this:

This error is also available in Glassfish 3. Working with ear projects does not permgen space make fun at all as long as the issue is not fixed. My productivity is during development is also decreased a lot!!!! Therefore I believe this issue is at least critical. Please download the ear file from http://localhost:8080/download/tutorials/struts2/struts2-multi-module-demo.zip. It comes from my tutorial at http://www.nabisoft.com/tutorials/struts2/maven-struts-2-enterprise-application-based-on-java-ee-7-and-glassfish-4, so please check there for details about what you can permgen space error find in the ear archive. Basically it is a Struts 2 project based on Java EE 7, Tiles, maven... The bug can be reproduced in Eclipse and Netbeans, so I guess this is not an Eclipse nor a Netbeans issue. To reproduce the bug do the following in your Netbeans IDE (or Eclipse): Make sure to adapt the persistence.xml in the struts2-module-ejb module and make sure the corresponding JDBC resource is available on your Glassfish 4 (for details see the tutorial, which uses a PostgreSQL database). import the project into Netbeans deploy to your local Glassfish 4 server from within Netbeans and wait until deployment has finished go to MessageServiceBean.java (struts2-module-ejb module), change something (i.e. add an empty line somewhere) save the change to trigger a re-deployment wait until re-deployment has finished in your browser hit http://localhost:8080/service/message/ (I think this step helps to make the bug occur earlier than without this step) check the glassfish output in netbeans repeat steps 4-7 ab
