Permgen Space Error In Tomcat 6
Recently I ran into this error in my web application: java.lang.OutOfMemoryError: PermGen space It's a typical Hibernate/JPA + IceFaces/JSF application running on Tomcat 6 and JDK 1.6. Apparently this can occur after redeploying an application a few times. What causes it and what can be done to avoid it? How do I fix the problem? java exception memory-leaks out-of-memory permgen share|improve this question edited May 11 at 12:58 community wiki error during sbt execution java lang outofmemoryerror permgen space 7 revs, 6 users 55%Chris I have fought this for hours, but I have no good news. See my related question: stackoverflow.com/questions/1996088/… You may still have a memory leak, e.g. classes are not garbage collected because your WebAppClassLoader is not garbage collected (it has an external reference that is not cleared). increasing the PermGen will only delay the OutOfMemoryError, and allowing class garbage collection is a precondition, but will not garbage collect classes if their class loader still has references to it. –Eran Medan Jan 14 '10 at 11:48 I got this error at adding display taglib. Removing so also solved the error. Why so? –masT Nov 14 '13 at 11:51 And how did you run into it? –Thorbjørn Ravn Andersen Feb 25 '14 at 4:16 10 use JDK 1.8 :þ welcome to the MetaSpace –Rytek Mar 20 '14 at 16:25 add a comment| 32 Answers 32 active oldest votes 1 2 next up vote 514 down vote accepted The solution was to add these flags to JVM command line when Tomcat is started: -XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled You can do that by shutting down the tomcat service, then going into the Tomcat/bin directory and running tomcat6w.exe.

Exception In Thread Main Java Lang Outofmemoryerror Permgen Space
2011 in Java Java Performance PermGen In this article, I look into what it ant java lang outofmemoryerror permgen space means when a Java program runs into a OutOfMemoryError: PermGen Space error. I first explain what the permanent generation heap tomcat7 java lang outofmemoryerror permgen space space is, after which I explain the usual cause of the Permgen Space error and I give some pointers on how to avoid it. Introduction Usually, we do not look into JVM intrinsics. We http://stackoverflow.com/questions/88235/dealing-with-java-lang-outofmemoryerror-permgen-space-error take the JVM as is. Some of the world’s finest engineers are working on the JVM(s) and I am sure we can’t improve their work, definitely not without getting seriously involved. However, as a Java developer, you are often confronted with performance issues, usually working memory related. The problem I run into most is the dreaded OutOfMemoryError: PermGen Space error. I thought it would be nice to know more http://www.integratingstuff.com/2011/07/24/understanding-and-avoiding-the-java-permgen-space-error/ about it, so I looked into what causes it exactly. Java memory structure To understand the error, we have to look into how the jvm memory is structured. There are two memory regions in the JVM: the heap and the stack. Local variables and methods reside on the stack, everything else on the heap. This Java heap memory is structured again into regions, called generations. The longer an object lives, the higher the chance it will be promoted to an older generation. Young generations(such as Eden on Sun JVM) are more garbage collected than older generations(survivor and tenured on Sun JVM). However, there is also some separate heap space called permanent generation. Since it is a separate region, it is not considered part of the Java Heap space. Objects in this space are relatively permanent. Class definitions are stored here, as are static instances. Without getting into details, Classloaders deploy and undeploy classes all the time. For example, this happens when an application is deployed or undeployed on a webserver. On web servers, all applications have their own Classloader. When an application is deployed or undeployed, its class definitions and Classloader are respectively put into and removed from the permanent generation heap. OutOf
