limits and JBoss needs a restart (java.lang.OutOfMemoryError: PermGen space). I found a solution for older JBoss version to increase the MaxPermSize. I guess the same goes for JBoss7. Which value would be good enough in order not to face any problem again? Is there any way to get permanently away from this problem (like lets say use a different VM like JRockit)? java-ee jboss webserver jboss7.x share|improve this question edited Nov 16 '12 at java.lang.outofmemoryerror permgen space in jboss server 7:39 Craig Ringer 134k18223306 asked Jul 25 '12 at 9:17 MaVRoSCy 11k94785 1 This really shouldn't be happening on AS 7 unless you're deploying a lot of big classes. Because of its modular classloader, JBoss AS 7 shouldn't suffer from classloader leaks which - combined with multiple redeploys during testing - are the most common cause of this problem on other servers. Do you get these errors only after lots of redeploys? Under what circumstances? –Craig Ringer Jul 31 '12 at 3:16 we have been testing our applications and during this phase we had extensive redeploys . And out of nowhere this problem struck –MaVRoSCy Jul 31 '12 at 5:36 Interestingly enought, I'm running the JBoss 7.1.1 on my windows server as a service. In this scenario, after the deployment it's dead. Running the server from standalone.bat, works solid as on my development machine. –feder Sep 8 '13 at 21:11 add a comment| 3 Answers 3 active oldest votes up vote 46 down vote accepted Since this happens after multiple redeploys it sounds like you've encountered a classloader leak, a common kind of permgen leak. These lovely beasts happen because of normal (non-weak) references from objects owned by the container to objects that're instances of classes loaded from the application classloader. If those references aren't cleared on

realized that the following out of memory error has occurred: java.lang.OutOfMemoryError:
Jboss Maxpermsize
PermGen space Cause: The Permanent Generation space stands for a fixed place in memory in which the java.lang.outofmemoryerror permgen space wildfly Virtual Machine stores "classes/bytecodes" and "class metadata". When this place, not managed by the Garbage Collector, gets full the error "java.lang.OutOfMemoryError: PermGen space" is issued. This type of http://stackoverflow.com/questions/11646483/jboss-7-java-lang-outofmemoryerror-permgen-space error could happen at application startup or using OutSystems J2EE Platform whenever huge deployment activities are performed. This happens because classes are able to be loaded not only during startup but sometimes on the fly due to Java dynamic behavior. Resolution: To overcome this occurrence one should adjust the memory Permanent Generation size according to https://www.outsystems.com/forums/discussion/3533/jboss-permgen-space-out-of-memory/ its needs in order to accommodate any outstanding memory demand. The MaxPermSize parameter should be increased in order to face any memory demand, a plausible value would be "-XX:MaxPermSize=1024m". MaxPermSize parameter is located in file: $JBOSS_HOME/bin/run.conf References: http://wiki.jboss.org/wiki/Wiki.jsp?page=OutOfMemoryExceptions ----------------------------------------------------- Best Regards Carlos Cabral Dislike(0)Like(1)Dislike(0)Like(1)Joao MeloPosted on 2014-08-18Joao MeloRank: #124Posted on 2014-08-18SolutionWe have been experiencing the same problem in our development environment. We restart jboss server every time this happens. Does anyone still experience this problem? Info: The conf file is now (Platform version 8) allocated at 'standalone-outsystems.conf'.

If you are having this frequently you can either have a too strict configuration, or be experiencing memory leaks in the classloader. How much PermGen do you have configured? How often does this happen? You can turn on GC logs on the standalone-outsystems.conf file to take a deeper look at the memory
août 2009 Anthony Dahanne 9 commentaires Once again, this infamous exception blew at my face when starting JBoss 4.2.3.GA today ! In fact, JBoss had to deploy 2 wars, one of them being a Web Service deploying war. This exception occurred https://blog.dahanne.net/2009/08/12/jboss-and-java-lang-outofmemoryerror-permgen-space/ for one simple reason : the permgenspace is where class properties, such as methods, fields, annotations, and also static variables, etc. are stored in the Java VM, but this space has the particularity https://confluence.atlassian.com/confkb/how-to-fix-out-of-memory-errors-by-increasing-available-memory-154071.html to not being cleaned by the garbage collector. So if your webapp uses or creates a lot of classes (I’m thinking dynamic generations of classes), chances are you met this problem. Here are permgen space some solutions that helped me get rid of this exception : -XX:+CMSPermGenSweepingEnabled : this setting enables garbage collection in the permgenspace -XX:+CMSClassUnloadingEnabled : allows the garbage collector to remove even classes from the memory -XX:PermSize=64M -XX:MaxPermSize=128M : raises the amount of memory allocated to the permgenspace These options must be included in the JAVA_OPTS part of your Jboss run.bat or run.sh startup file.

in Atlassian Cloud apps, the contents of this article cannot be applied to Atlassian Cloud applications. Purpose Java applications like JIRA, Crowd and Confluence run in a "Java virtual machine" (JVM), instead of directly within an operating system. When started, the Java virtual machine is allocated a certain amount of memory, which it makes available to applications like Confluence. By default, Java virtual machines are allocated 64Mb of memory, no matter how many gigabytes of memory your server may actually have available. 64Mb is inadequate for most Confluence installations, and so this needs to be increased. Diagnosis Expand to see diagnosis section Determine type of error message Look in the atlassian-confluence.log to see which type of OutOfMemory Error you're receiving. There are three common messages: Heap Space Perm Gen Space GC Overhead This document discusses increasing memory to address PermGen and Heap space errors. Follow the links above to assess root causes for each issue. For GC Overhead, refer to Confluence Crashes Due to 'java.lang.OutOfMemoryError GC overhead limit exceeded'. Determine Confluence's usage patterns In Confluence, go to Confluence Administration > System Information , and look at the memory graph during times of peak usage: This server has been allocated a maximum of 650Mb and a minimum of 256m. You can see the minimum displayed here; if you're trying to see whether your settings are being picked up, this is where to look. Determine available system memory On Windows From the Close Programs Dialogue (Press ctrl-alt-delete), select the Performance tab: The amount marked Available is the amount in kilobytes you have free to allocate to Confluence. On this server we should allocate at most 214Mb. On Linux Run cat /proc/meminfo to view the memory usage. Setting the -Xmx above the available amount on the server runs the risk of OutOfMemoryErrors due to lack of physical memory. If that occurs the system will use swap space, which greatly decreases performance. Guidance The default values supplied with Confluence stand-alone are sufficient for most installations. Please refer to Managing Application Server Memory Settings and Server Hardware Requirements Guide for a discussion. Solution Step 1: Increase
