Maat 6:42 am The snippet in the eclipse.ini vm argument Mac section helped me fix a problem encountered yesterday.Īfter installing new JDKs for Java14 and new JDK8, STS 4 wouldnt start (saw error message Unable to create Java Virtual Machine). Heap Space If you are getting OutOfMemoryError related to Heap space, then you can try to increase the maximum heap size available to eclipse.įor example, below snippet will increase the eclipse heap size to 2 GB.Īt 2:02 am i have tizen studio and increased XMS to 512 M and try to build project but it shows jvm terminated error exit 1. However you will also not get out of memory error because of permgen space.

Mac My eclipse.ini file snippet showing -vm argument usage to configure eclipse to use JDK8 in Mac OS X.īelow is the configuration to increase permgen space to 512 MB in eclipse.ini file. Permgen space default value is configured as 256MB that is good for small to medium projects. They are configured using VM arguments -XX:MaxPermSize, -Xms and -Xmx. If you are getting Out of Memory errors, you should try to increase Permgen space and maximum heap space values. XXMaxPermSize specifies the maximum permgen space to use by eclipse launcher, increase this value if your eclipse startup is failing with out of memory error. Here is the example eclipse.ini file from my default eclipse installation.Īll the lines after -vmargs are passed as JVM arguments, so all options and arguments for eclipse startup must be specified before -vmargs.įor example -vm settings for JDK to be used. So if Eclipse app is in Downloads directory, eclipse.ini file location will be. Table of Contents 1 eclipe.ini File Location 2 eclipse.ini vm argument 2.1 eclipse.ini vm argument Mac 3 eclipse.ini Permgen Space 4 eclipse.ini Heap Space eclipe.ini File Location For windows, its in the same directory as eclipse.exe file, as shown in below image. Setting Javapath For Eclipse Mac 3 Eclipse We can configure Eclipse VM arguments such as JDK to be used (eclipse.ini vm), permgen space, maximum and minimum heap size using Xms, Xmx parameters.

for example: java -Xm圆gģ) Also, if you don’t have memory leaks in your application, it is recommended to upgrade to a newer version of JDK which uses the G1GC algorithm. That should be also evident by clicking on the See Stracktrace link, which will print the stack trace of that Thread.Ģ) If you cannot find any memory leak, increase the heap size if current heap is not enough. If you click on the “Details” link you will see some more info about where the instances reside and why they are so big. Then, open the Heap Dump with Eclipse Mat and generate a Leak Suspect report as in this example:Īs you can see, MAT has found one leak suspect, which occupies 71% of application’s memory, taken by instances of class. To do that, include the following option in your JVM, so that an Heap dump will be created upon an Out of Memory error: -XX:+HeapDumpOnOutOfMemoryError This is meant to prevent applications from running for an extended period of time while making little or no progress reclaiming objects.īefore talking about the possible solution, it is worth to know that this feature can be disabled with the following option: java -XX:-UseGCOverheadLimitĭisabling this throttle however, will just postpone the memory issue that will turn soon into a “: Java heap space.”ġ) Check for Memory leaks with a memory profiling tool like Eclipse MAT ( ), Visual VM etc and fix any memory leaks.

This exception is typically thrown because the amount of live data barely fits into the Java heap having little free space for new allocations. After a garbage collection, if the Java process is spending more than approximately 98% of its time doing garbage collection and if it is recovering less than 2% of the heap and has been doing so far the last 5 consecutive garbage collections, then a thrown. Let’see how to solve it.Īccording to the JDK Troubleshooting guide, the “ : GC overhead” limit exceeded indicates that the garbage collector is running all the time and Java program is making very slow progress. The error “ : GC overhead limit exceeded” is fairly common for old JDK (mostly JDK 1.6 and JDK 1.7).
