(OOM) on S ...Increase Eclipse Memory Size to avoid OutOfMemory (OOM) on Startup - Java Heap Space Last Updated on 16 December, eclipse maxpermsize 2014 by App Shah Leave a Comment Are you running heavy Java projects in Eclipse? Is garbage collection happening too fast? Eclipse is consuming lots of CPU or Memory resource? In my case, while running Eclipse project, I recently got Out Of Memory (OOM) error. There error occurred during initialization of vm could not reserve enough space for 1560576kb object heap are some simple tuning required in order to fix it. Below hack worked for me. Tuning Eclipse Performance and Avoiding OutOfMemory Exceptions Go to your Eclipse setup folder If you are running Eclipse on Mac OS X then Right click on eclipse.app icon Click on Show Package Contents Open eclipse.ini file Change below parameters -Xms512m -Xmx3000m (Hoping your developer box has >4GB of memory) Add below parameters -XX:PermSize=256m -XX:MaxPermSize=512m Also, if you are running Eclipse from command prompt, use below parameters: 123456 C:\Program Files\eclipse\eclipse.exe-vmargs-Xmx1800m-Xms512m-XX:PermSize=256m-XX:MaxPermSize=512m -XX:PermSize specifies the initial size that will be allocated during startup of the JVM. If necessary, the JVM will allocate up to -XX:MaxPermSize. This is what my eclipse.ini file looks like: eclipse.ini file 12345678910111213141516171819202122232425 -startup../../../plugins/org.eclipse.equinox.launcher_1.3.0.v20140415-2008.jar--launcher.library../../../plugins/org.eclipse.equinox.launcher.cocoa.macosx.x86_64_1.1.200.v20140603-1326-productorg.eclipse.epp.package.jee.product--launcher.defaultActionopenFile-showsplashorg.eclipse.platform--launcher.XXMaxPermSize256m--launcher.defaultActionopenFile--launcher.appendVmargs-vmargs-Dosgi.requiredJavaVersion=1.6-XstartOnFirstThread-Dorg.eclipse.swt.internal.carbon.smallFonts-XX:MaxPermSize=1024m-Xms200m-Xmx4000m-Xdock:icon=../Resources/Eclipse.icns-XstartOnFirstThread-Dorg.eclipse.swt.internal.carbon.smallFonts Have a suggestion on article?

Java Heap Space Error In Eclipse Kepler
takes a minute: Sign up Can't solve “Java heap space” error in eclipse up vote 1 down vote favorite While running my Java code in Eclipse IDE, I got the error: Exception in thread "D3D Screen Updater" Exception in thread http://crunchify.com/increase-eclipse-memory-size-to-avoid-oom-on-startup/ "AWT-EventQueue-0" java.lang.OutOfMemoryError: Java heap space I searched for this error and tried solutions described here and here, but they did not work. I changed these parameters in eclipse.ini: --launcher.XXMaxPermSize 512M -Xms40m -Xmx512m to: --launcher.XXMaxPermSize 1024M -Xms512m -Xmx2048m EDIT: I changed this parameters at Run Configurations: But I still get the same error.

I guess the program is blowing something out. It could be heap, or it could be something else. You could enable verbose GC logging and/or run the program in debug mode from Eclipse. If the problem takes some time to fail, you can attach a profiler to it, like VisualVM or jconsole (found in the JDK bin directory). Finally, you can config the VM to dump heap on OOMs. –jdv Nov 25 '14 at 17:13 Oh, I guess we should ask: did you roll back those Eclipse.ini changes you made? Because those resources are shared, and, especially on Windows, you are going to get resource contention fast if Eclipse is grabbing all the PermGen or whatever. –jdv Nov 25 '14 at 17:16 Finally, the assumption is that this program throws an OOM if run standalone, and not via Eclipse. You should prove this assumption is correct. –jdv Nov 25 '14 at 17:21 add a comment| 4 Answers 4 active oldest votes up vote 1 down vote accepted Where is the "vmargs" option? If you set the min/max heap, you probably need to do it on the main process, not the launcher. See the Eclipse FAQ item on setting VM options. That launcher PermSize opt is a bit ridic

Some JVMs put restrictions on the total amount of memory available on the heap. If you are getting OutOfMemoryErrors while running Eclipse, the VM can be told to let the heap grow to a larger amount by passing the -vmargs out of memory command to the Eclipse launcher. For example, the following command would run Eclipse with a heap size of 256MB: eclipse [normal arguments] -vmargs -Xmx256M [more VM args] 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 VMs. You can also put the extra options in eclipse.ini. Here is an example; -startup plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar --launcher.library plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.200.v20120913-144807 -showsplash org.eclipse.platform --launcher.XXMaxPermSize 256m --launcher.defaultAction openFile -vmargs -Xms512m -Xmx1024m -XX:+UseParallelGC -XX:PermSize=256M -XX:MaxPermSize=512M See Also: FAQ How do I run Eclipse?
