When I run my Java code in Eclipse, I get the following message:
There is insufficient memory for the Java Runtime Environment to continue.
Native memory allocation (malloc) failed to allocate 4088 bytes for AllocateHeap
An error report file with more information is saved as:
E:\Eclipse_Workspace\BTest\hs_err_pid1888.log
I have 4GB RAM in my computer. I have changed my JRE from 1.7 to 1.8 too. But the issue seems un-resolved. I use a Win 8 system with i3 Processor and have around 20gb of free disk space in my C Drive.
Eclipse version: Eclipse Juno Service release 2
I also get this message while starting Eclipse. I have attached the error message screen shot.
What is causing this issue?

Resolution:
Re-installing eclipse fixed the problem.
The message above means that you're running so many programs on your PC that there is no memory left to run one more. This isn't a Java problem and no Java option is going to change this.
Use the Task Manager of Windows to see how much of your 4GB RAM is actually free. My guess is that somewhere, you have a program that eats all the memory. Find it and kill it.
EDIT You need to understand that there are two types of "out of memory" errors.
The first one is the OutOfMemoryException which you get when Java code is running and the Java heap is not large enough. This means Java code asks the Java runtime for memory. You can fix those with -Xmx...
The other error is when the Java runtime runs out of memory. This isn't related to the Java heap at all. This is an error when Java asks the OS for more memory and the OS says: "Sorry, I don't have any."
To fix the latter, close applications or reboot (to clean up memory fragmentation).
How to diagnose this error even when running the simple command:
java -version
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Cannot create GC thread. Out of system resources.

Check the amount of free memory you have:
free -m

For me, the reason this happened was because PHP had consumed too much memory allocated to me on bluehost, and the way I was able to fix it, without restarting PHP or the server ( I can't ) was to take the public_html directory and rename it. And give it a minute for PHP to see the change, then rename it back.
A bug in the php engine itself. I found a clever way to give the PHP engine a swift kick.
(update Feb 2016) (I'm getting a spike of up-votes on this because Bluehost instance PHP engines are reserving all the memory and leaving none for the JVM. In their defense, PHP is evolving into an unholy rube Goldberg machine. Bluehost as a service is on the decline.
If you are on ec2 and wanted to do mvn build then use -T option which tells maven to use number of threads while doing build
eg:mvn -T 10 clean package
If you are using Virtual Machine (VM), allocate more RAM to your VM and your problem will be solved.
In your Eclipse installation directory you should be able to find the file eclipse.ini. Open it and find the -vmargs section. Adjust the value of:
-Xmx1024m
In this example it is set to 1GB.
Try to modify your eclipse.ini with below
-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20120913-144807

Once you open your eclipse you can try below
Looks like your application consumes more memory than allocated (Default). I will try two things
As suggested by Harmlezz increase your memory allocation to JVM to -Xms2g -Xmx2g (If needed increase it more and try it out)
Download eclipse memory analyzer and check for what causing memory leak OR even you can use JConsole to see JVM memory utilization in order to figure out application memory leak issue.
It is quite simple to fix, I am not sure why no one mentioned the actual working solution.
Firstly, make sure, Wireless Hotspot is Turned Off. That's most important, while building the Project, the Hotspot must not be On.
Do this, and Thanks me later 💖
Secondly, set the Environment Variables into your system, and Thirdly disable the firewall or antivirus for Android Studio & Java VM. It will definately fix your issue.

In my case it was that I manually set the Windows virtual memory too low to save space in the system SSD.
You need to diagnosis the jvm usages like how many process is running and what about heap allocation. there exists a lot of ways to do that for example
you can use java jcmd to check number of object, size of memory (for linux you can use for example "/usr/jdk1.8.0_25/bin/jcmd 19628 GC.class_histogram > /tmp/19628_ClassHistogram_1.txt", here 19628 is the running application process id). You can easily check if any strong reference exists in your code or else.
I know the question talking about eclipse but i got the similar issue many times with Intellij as well and the solution for it was easy .. Just run the 64 bit exe not the 32 one which is always the default one.
In my case it was that the C: drive was out of space. Ensure that you have enough space available.

I already searched for this issue but i can't got any good solution,any help is really appreciated.
May be you can try following
Increase from -Xms40m to -Xms500m. It indicates jvm to start with 500 Mb memory.
Try with STS –clean
Remove file <WORK_SPACE>/.metadata.plugins\org.eclipse.core.resources.projects\.markers.snap, because sometimes eclipse will constantly polling a fairly large snapshot of some of your projects.
You can disable ‘Refresh workspace on startup’ option in Windows -> Preferences -> General -> Startup and Shutdown
Disable automatic builds under Install/updated and Label Decorator
Upgrading to the latest JVM supported on your machine this may help as well
Disable all validations under preferences unless you need them
I hope these tips will help you for sure :) .
My STS was taking a long time, 5 minutes just to boot up, in spite of running on a high performance SSD machine. So I modified the STS.ini with Xms=200m(original value was 40m) and it started booting up real fast in under 30 seconds.

--add-modules=ALL-SYSTEM
-Xms300m

-Dorg.eclipse.swt.browser.IEVersion=10001

STS is based off eclipse so some the answers on this site re speeding up eclipse will help.
I noticed a great speed up by installing a Solid State Drive. This
speeds up your whole machine.
Using the latest oracle JDK speeds things up for me too.
I m using Eclipse Indigo. It becomes unresponsive often and finally prompts saying out of memory error and asks me to exit workbench. I increased the Perm Gen space as told in one of the eclipse forums by editing my eclipse.ini file.

I mostly do Javascript development in eclipse. And I am not able to edit JS file in eclipse.
What can I do to solve this problem?
Currently maximum only 512MB is allowed for eclipse in your ini (-Xmx512m), if you have enough RAM you shall try increasing it to 1GB. More info here http://wiki.eclipse.org/FAQ_How_do_I_increase_the_heap_size_available_to_Eclipse%3F
This problem may be due to
You are using old java version , You need to upgrade it with new version
If your operation system is 64 bit make sure that you are using 64bit java
Java 5 is pretty old. The GC (and overall optimizations) are slow, outdated and patch level 15 means you're missing many critical bug fixes.
The first step would be to install Java 7 (lastest version). Make sure you disable the browser plugin because of the security risks.
Then make sure that Eclipse uses it: Update the path after -vm. Note: If your path contains spaces, use this:
-vm
c:\Program Files\Java\...
(i.e. put the path into a line of it's own).
Lastly, there are two kinds of memory in Java. Heap and PermGen. The error message tells you which one ran out. Use -Xmx to set heap memory and -XX:MaxPermSize= for PermGen. 256m PermGen should be enough but some script languages need more.
With Java 7, enable GC1 which should give you better performance: -XX:+UseG1GC
If I run my GWT application in eclipse in development mode and click around in the browser for some time, I always get an "out of memory" error in eclipse. My computer has 16 GB Ram, and there is never used more than 8GB.
I tried several config parameters. The VM-arguments in my Run configuration contain these parameters: "-Xms8192m -Xmx8192m"
Even in the eclipse.ini I tested several config parameters and now it looks like this:
--launcher.XXMaxPermSize
8192M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
8192m
--launcher.defaultAction
openFile
--launcher.appendVmargs
-vmargs
-Dosgi.requiredJavaVersion=1.6
-Xms8192m
-Xmx8192m
But I still get the error. Is there any way to prevent this?
If the browser application is throwing the OutOfMemoryError, then you don't need to change the Eclipse settings (eclipse.ini), that's only for Eclipse itself (more memory, usually faster workbench).
To increase an app's memory (any Java app launched from Eclipse), go to the Run/Debug configurations... in the Run menu and set the VM arguments on the Arguments tab of the app's run config:
-Xms128M -Xmx1024M -XX:MaxPermSize=256M
put this in vm arguments in your run configurations:
-Xmx2048M -XX:MaxPermSize=512m
If I run my GWT application in eclipse in development mode and click around in the browser for some time, I always get an "out of memory" error in eclipse.
Not exactly sure what the problem is but I do see some issues with your current arguments.
You have 2 launcher args that are the same. You don't need the 2nd entry of:
--launcher.XXMaxPermSize
8192M
I really doubt that you want 8g of PermSize. Something like 512m is probably much better. You can use jconsole to see how much memory is in the perm space bucket. In the below image taken from jconsole's memory tab, the bar highlighted at the bottom right shows the "Perm Gen" space. Right now it is using 26,906kb (or around 27mb). That's where code goes and it often has to be increased if you have many JSP pages which get compiled as well.
If you run your application with the following params you should be able to connect with jconsole to see how it's doing:
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.authenticate=false
I suspect that you are going to see that you are using far, far less in the "Perm Gen" space. The -Xmx8192m (or -Xmx8g) is all you need typically. It will give 8gb of memory to the heap in general which is typically short lived objects. It also scales the various different memory partitions accordingly.
For more information about various heap spaces see the Java hotspot documentation.
I am getting below error while starting eclipse
An internal error occurred during: "Updating indexes".Java heap space?
It was running fine half an hour before.I restarted the eclipse and getting this error now? i have 8 gb ram,window 7 64 bit OS.
i have tried restarting my system but nothing helped?

If you have m2e or other Maven plugin installed, you should check if the option at 'Window -> Preferences -> Maven -> Download repository updates index on startup' is enabled. Disable it and see if it resolves out of memory issue.
If you are using eclipse or myeclipse, you can increase memory by making changes in .ini file (myeclipse.ini)
-Xmx2048m
-XX:MaxPermSize=1024m
-XX:ReservedCodeCacheSize=512m
-Dosgi.nls.warnings=ignore
It will solve problem connected with heap space.
Assuming this is a heap space problem, try this FAQ:
Eclipse-Wiki: FAQ How do I increase the heap size available to Eclipse?
This may not be directly related to the question, but this fixed the java heap issues I had:
Launch eclipse using eclipse -vmargs -Xmx2048m.
From the readme included with the eclipse install:
By default, Eclipse will allocate up to 512 megabytes of Java heap
memory. This should be ample for all typical development tasks.
However, depending on the JRE that you are running, the number of
additional plug-ins you are using, and the number of files you will be
working with, you could conceivably have to increase this amount.
Eclipse allows you to pass arguments directly to the Java VM using the
-vmargs command line argument, which must follow all other Eclipse specific arguments. Thus, to increase the available heap memory, you
would typically use:
eclipse -vmargs -Xmx<memory size>
with the value set to greater than "512M" (512 megabytes
-- the default).
Old question, but I got this issue and adding more memory did not solve, so I rebuilt the java index by applying this comment from eclipse bug tracker:
I Quote:
Click in "Quick Access", Type "Rebuild Java Index" (Actually just start typing it, use the auto completion), Hit enter.
I'm currently developing a tool allowing me to get statistics from anyware simply by going on a website I also created.
For those who don't know, Birt is a reporting tool, and an eclipse plugin.
My problem is the following :
I installed tomcat on the server hosting my website, and installed the Birt ReportEngine on it, and on my website, I call the online viewer to get my reports.
The problem is that since yesterday, when I launch a report, I have this error :
javax.servlet.ServletException: L'exécution de la servlet a lancé une exception
org.eclipse.birt.report.filter.ViewerFilter.doFilter(ViewerFilter.java:68)
Caused by :
java.lang.OutOfMemoryError: PermGen space
I don't really know which config file to modify to avoid this error. I found some examples online that tell to modify the eclipse.ini file, but as for mty website, I don't use eclipse, I didn't found any usefull post.
Can someone help me please ?
Thanks
As said by Thomas, the parameter to set is -XX:MaxPermSize. One way of setting this parameter for Tomcat is to use the CATALINA_OPTS environment variable.
For Windows :
set CATALINA_OPTS=-Xms512m -Xmx512m -XX:MaxPermSize=256m
For Linux (bash) :
export CATALINA_OPTS="-Xms512m -Xmx512m -XX:MaxPermSize=256m"
Check the startup.bat and catalina.bat or startup.sh and catalina.sh files in your tomcat/bin directory and add the above commands there.
(The Xmx and Xms parameters set the minimum and maximum size for the Java heap - where objects are stored. This is not the problem you have but I included them for the sake of completeness.)
You need no add the following line to eclipse.ini
-XX:MaxPermSize=128m
If the problem occurs again try to increase the value. You can also add the following optional lines:
-XX:+UseConcMarkSweepGC
-XX:+CMSClassUnloadingEnabled
-XX:+CMSPermGenSweepingEnabled
-XX:+UseParNewGC
This changes the Garbage Collector of the JVM to a more optimized one, and can also improve the performance and memory usage.
You may also want to tweak the values of the -Xmx and Xms options. Try small increases (same to the -XX:MaxPermSize) as this will increase the memory footprint of your JVM.
For a more explained details see here:
http://www.eclipsezone.com/eclipse/forums/t61618.html
For a complete list of the JVM parameters and options:
http://www.oracle.com/technetwork/java/javase/tech/vmoptions-jsp-140102.html
Use that JVM option: -XX:MaxPermSize=256m (of course you are free to choose the amount of memory, but IIRC the default would be 64m so you'd need to increase that). - Note that this is for Oracle's JVM (formerly SUN's :) ) , other JVM's might have different options.
Other than that, try not hot deploying too much, since that might also increase the PermGen space usage (JBoss which includes Tomcat as has that problem, but I'm not sure whether that is true for a standalone Tomcat).
This can be solved by allocating more heap memory.
this can be done as:
steps:
double click on your eclipse server->open launch configuration->Arguments->paste this line in vm arguments text area:-
-XX:MaxPermSize=512M -Xmx1024M
This will solve your outofmemory error.
I added the below line line to eclipse.ini and working fine for me.
