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 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.

in Java Everyone in java development faces java.lang.OutOfMemoryError now and then, OutOfMemoryError in Java is one problem which is more due to system's limitation (memory) rather than due to programming mistakes in most cases though in certain java.lang.outofmemoryerror: permgen space maven cases you could have a memory leak which causing OutOfMemoryError. I have found that java.lang.outofmemoryerror permgen space jboss even though java.lang.OutOfMemoryError is quite common basic knowledge of its cause and solution is largely unknown among junior developers.

books like Head First Java doesn't teach you much about how to deal with this kind of error. You need real experience dealing with production systems, handling a large number of user sessions to troubleshoot http://stackoverflow.com/questions/88235/dealing-with-java-lang-outofmemoryerror-permgen-space-error and fix performance issues like running out of memory. If you want to be good at troubleshooting and performance analysis, you need to learn some books on Java performance and profiling e.g. Java Performance The Definitive Guide By Scott Oaks or the Java Performance by Binu John. They are an excellent resource for senior Java developers and also teaches you tools and process to deal with an error like http://javarevisited.blogspot.com/2011/09/javalangoutofmemoryerror-permgen-space.html java.lang.OutOfMemoryError. In this article, we will explore what is java.lang.OutOfMemoryError; Why OutOfMemoryError comes in Java application, different type of OutOfMemoryError and How to fix OutOfMemoryError in Java. This article is purely meant to provide basic knowledge of java.lang.OutMemoryError and won't discuss profiling in detail. For profiling read the books I have mentioned before. What is java.lang.OutOfMemoryError in Java OutOfMemoryError in Java is a subclass of java.lang.VirtualMachineError and JVM throws java.lang.OutOfMemoryError when it ran out of memory in the heap. OutOfMemoryError in Java can come anytime in heap mostly while you try to create an object and there is not enough space on the heap to allocate that object. Javadoc of OutOfMemoryError is not very informative about this, though. Types of OutOfMemoryError in Java I have seen mainly two types of OutOfMemoryError in Java: 1) The java.lang.OutOfMemoryError: Java heap space 2) The java.lang.OutOfMemoryError: PermGen space Though both of them occur because JVM ran out of memory they are quite different to each other and their solutions are independent of each other. The difference between "java.lang.OutOfMemoryError: Java heap space" and "java.lang.OutOfMemoryError: PermGen space" If you are familiar with different generations on the heap and How garbage collection works in java and aware of new, old a
