Permgen Space Jenkins
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 7 revs, 6 users 55%Chris I have fought this for permgen space gradle 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 515 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. Under the "Java" tab, add the arguments to the "Java Options" box. Click "OK" and then restart the service. If you get an error the specified service does n

Permgen Java
If you get the error message: java.lang.OutOfMemoryError: PermGen space this means that you have exceeded permgen space java 8 Java's fixed block for loading class files. Permanent Generation Memory, unlike Java heap space, is the memory allocation for the classes themselves as opposed to the http://stackoverflow.com/questions/88235/dealing-with-java-lang-outofmemoryerror-permgen-space-error objects created. The addition of more plugins contributes to more consumption of PermGen space. The error occurs when enough classes are invoked. Resolution This is only relevant for Confluence 5.7 and below as Java 8 manages PermGen automatically. To avoid this in the future follow the steps detailed in the guide https://confluence.atlassian.com/confkb/confluence-crashes-due-to-outofmemoryerror-permgen-space-126910596.html How to fix out of memory errors by increasing available memory. Find the instructions on how to increase the Permanent Generation Space. Make sure to change -XX:MaxPermSize rather than the Heap Space Parameters. Confluence doesn't require a huge amount of PermGen memory, so if you find that you need to increase it to more than 512MB this could indicate a problem with either the application or an installed addon.

Note: Oracle Java 8 does not have a separate permanent generation space any more. The -XX:(Max)PermSize option makes no difference (the JVM will ignore it, so it can still be present). If you see java.lang.OutOfMemoryError: PermGen space errors, you need to increase the permanent generation space available to Eclipse. PermGen error permgen space is the permanent generation of objects in the VM (Class names, internalized strings, objects that will never get garbage-collected). An easy, if somewhat memory-hungry fix is to enlarge the maximum space for these objects by adding -XX:MaxPermSize=128M as an argument to the JVM when starting Eclipse. The recommended way to do this is via your eclipse.ini file. Alternatively, you can invoke the Eclipse executable with command-line arguments directly, as in eclipse [normal arguments] -vmargs -XX:PermSize=64M -XX:MaxPermSize=128M [more VM args] Note: The arguments after -vmargs are directly passed to the VM. Run java -X for the list of options your VM accepts. Options starting with -X are implementation-specific and may not be applicable to all JVMs (although they do work with the Sun/Oracle JVMs). Eclipse and Sun VMs on Windows Eclipse 3.3 and above supports an argument to the launcher: --launcher.XXMaxPermSize. On Windows, Eclipse ships with the following lines in the eclipse.ini file: --launcher.XXMaxPermSize 256m With the above arguments, if the VM being used is a Sun VM and there is not already a -XX:MaxPermSize= VM argument, then the launcher will automatically add -XX:MaxPermSize=256m to the list of VM arguments being used.
