Increase Permgen Space Jboss 7
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 7:39 Craig
Java.lang.outofmemoryerror Permgen Space In Jboss Server
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 undeploy there's s

occurred: java.lang.OutOfMemoryError: PermGen space Cause: The Permanent Generation space stands for a fixed place in memory java.lang.outofmemoryerror permgen space wildfly in which the 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 http://stackoverflow.com/questions/11646483/jboss-7-java-lang-outofmemoryerror-permgen-space issued. This type of 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 https://www.outsystems.com/forums/discussion/3533/jboss-permgen-space-out-of-memory/ memory Permanent Generation size according to 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".

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 o
restarts because of it. This has been a nuisance for quite a while. Basically what happens is that every time you (re)deploy an application to JBoss, the java process takes up a bit more http://blog.yannis-lionis.gr/?p=8 memory, until after enough redeployments it runs out. This blog gives a very good http://www.ibm.com/support/docview.wss?uid=swg21390229 explanation of what the PermGen memory error is, how to monitor it and how to modify how much is available for your application. This however did not solve the problem, as increasing the available PermGen space simply delayed the inevitable. The memory used by JBoss only goes up after each redeployment, so the painful end is unavoidable. After chasing around the permgen space truth in various forums and blogs, each one suggesting a different culprit for the problem (Tomcat, cglib library, the combination of the two, Hibernate, and more) a colleague got a chance at a conference to ask some JBoss guys themselves for an answer. And an answer we got indeed: This problem happens with the Sun JVM. Use another one and it will go away. So I did. I tried JRockit. And it worked. The problem went away. java.lang.outofmemoryerror permgen space That simple. So if you have the same problem, give it a try. It worked for me and it made my day. 19 Responses to ""java.lang.OutOfMemoryError: PermGen space" in JBoss" on 16 Jul 2008 at 8:17 am # sree JRockit doesn't have generational garbage collection - in other words, it doesn't have permanent generation space. Therefore, it can't have PermGen errors. Ever. on 30 Oct 2008 at 8:20 pm # scozad You might also want to try updating to beanutils 1.8.0 it fixes redplyment leaks… http://www.jboss.org/feeds/post/redeployment_leaks_fixed_on_apache_beanutils on 06 Nov 2008 at 8:55 pm # MarcB JRockit … does that mean I need to switch from jBoss to BEA WebLogic Application server, or can I just install it? Do I need to install it on the server that runs muy JVM or on the machine that loads the applications hosted by the JVM? on 07 Nov 2008 at 12:13 am # Yannis Lionis No need to switch to Weblogic. Just download JRockit, install it on the server that JBoss is running on, and modify the JBoss startup script to use that jre instead of the one you were using so far. on 07 Nov 2008 at 7:46 am # MarcB ok, thanks, will give it a try. on 09 Feb 2009 at 8:13 pm # Ameya Bhakay Yannis, Thanks for this
