I was wondering if someone could explain why my eclipse is crashing. Eclipse says its trying to build and then there is a message not responding and I receive this message as eclipse close in figure 1
figure 1
The startup jvm memory allocated to eclipse seems to be low, in the screenshot provided:
-Xms40m -Xmx512m
Increasing these values might provide eclipse more memory to build project.
(Try closing all unused projects in the eclipse workspace)
Assuming your machine has RAM > 2-3 GB,
Modify the file eclipse.ini (in your case at C:\eclipse\eclipse.ini)
Update values of '-Xms' and '-Xmx' to following
....
-Xms512m
-Xmx1024m
The problem is Memory dedicated to eclipse .
this is the way my problem solved
fist :~>locate eclipse.ini
/home/ your - user /eclipse/eclipse.ini
Second
vi /home/ your - user /eclipse/eclipse.ini
-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20140415-2008.jar
--launcher.library

--launcher.appendVmargs
-vmargs
-Dosgi.requiredJavaVersion=1.7
-XX:MaxPermSize=1024m
-Xms512m

Then change This lines
--launcher.XXMaxPermSize
512m // mine was 256
-XX:MaxPermSize=1024m // mine was 512
-Xms512m // mine was 40
-Xmx2048m // mine was 512
Done :)

Fisrt I got an error "eclipse out of memory error and gc overhead limit exceeded" and,
Then I tried looking for the answer, and then found this.
After I edited the .ini just like Silvio's answer my eclipse won't start.
It just disappear after chosing workspace folder.
Edit :
I already tried opening a new eclipse and still eclipse won't start.
Entries in the eclipse.ini file :
-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

-vmargs
-Xms1024m
-Xmx1024m

-XX:PermSize=1024M
-XX:MaxPermSize=1024M
I hope fix your problem.
My STS stops responding within few minutes after the Workspace is built. What might be the possible reason for this?
I removed below property from STS.init, now it is working fine for me.
--add-modules=ALL-SYSTEM
try increasing the memory it's allowed to use in the STS.ini file
C0243321#IKHCPKISBN0084S /cygdrive/c/opensource/sts-bundle/sts-3.6.4.RELEASE

If you are using any antivirus then turn off when using STS.
Its works for me.
you can open file STS.ini and add
openFile
-C:\Program Files\Java\jdk1.8.0_191\bin\javaw.exe
I use Eclipse Kepler SR2 on Ubuntu 14.04 and the following is my eclipse.ini
-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20130327-1440.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.200.v20140116-2212

-vmargs -Dorg.eclipse.swt.browser.XULRunnerPath=/DevTools/xulrunner -Dorg.eclipse.swt.browser.Defau$
-Dosgi.requiredJavaVersion=1.6
-XX:MaxPermSize=3072m
-Xms2048m
-Xmx3072m
But in eclipse the heap size shows the following:
397 of 453M
And if I mouse over on the Heap size info it shows:
Heap size: 397M of total: 453M max: 455M mark: 397M
I am expecting the max value should be close to 3072M since that is what being set in eclipse.ini
Any insight is appreciated.
Each entry in the eclipse.ini must be on a separate line, your line:
-vmargs -Dorg.eclipse.swt.browser.XULRunnerPath=/DevTools/xulrunner -Dorg.eclipse.swt.browser.Defau$
will not be recognized as the start of the VMargs. It should be:
-vmargs
-Dorg.eclipse.swt.browser.XULRunnerPath=/DevTools/xulrunner
... more args on separate lines ...
I think manual installations cause such problems as my eclipse ignores eclipse.ini completely when run via the launcher in Ubuntu (14.04) (used lock to launcher). So the workaround for me is to run it any other way. Desktop icon works too. Property Path must be set within that file.
I am trying to increase the max heap size for my Eclipse. I have tried specifying in eclipse.ini or through the command line, but are not working.
My max heap size has the exact same limit before (running jconsole) and after (System.out.println(java.lang.Runtime.getRuntime().maxMemory());) starting Eclipse. 1.8G
Is there any way to modify JVM heap size before it is launched (ex. a config file?)
What could I be doing wrong when specifying heap size to Eclipse?
This is the command:
./eclipse/eclipse -debug -consoleLog -vmargs -Xms1000m -Xmx6000m -XX:-UseGCOverheadLimitcl
This is my eclipse.ini (which values are overwritten by the specified eclipse launching parameters):
-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.v20120522-1813

org.eclipse.platform
--launcher.XXMaxPermSize

--launcher.defaultAction
openFile

It is possible to increase heap size allocated by the Java Virtual Machine (JVM) by using command line options.
-Xms<size> set initial Java heap size
-Xmx<size> set maximum Java heap size
-Xss<size> set java thread stack size
If you are using the tomcat server, you can change the heap size by going to Eclipse/Run/Run Configuration and select Apache Tomcat/your_server_name/Arguments and under VM arguments section use the following:
-XX:MaxPermSize=256m
-Xms256m -Xmx512M
If you are not using any server, you can type the following on the command line before you run your code:
java -Xms64m -Xmx256m HelloWorld
More information on increasing the heap size can be found here
You can use this configuration:
-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
Try to modify the eclipse.ini so that both Xms and Xmx are of the same value:
-Xms6000m
-Xmx6000m
This should force the Eclipse's VM to allocate 6GB of heap right from the beginning.
But be careful about either using the eclipse.ini or the command-line ./eclipse/eclipse -vmargs .... It should work in both cases but pick one and try to stick with it.
--launcher.XXMaxPermSize
256m
Try to bump that value up!
I am working on a project which is really big and even if I increase the virtual memory, on refreshing the project, Eclipse crashes. The error is java heap space error.
This is the current setup:
-startup
plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.0.200.v20090519
-product
org.eclipse.epp.package.jee.product
--launcher.XXMaxPermSize
512M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
512m
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms256m
-Xmx512m
If I increase it any more, Eclipse won't start.
A few comments:
You shouldn't define twice launcher.XXMaxPermSize
You shouldn't use 512M (only 512m, see "FAQ How do I increase the permgen size available to Eclipse?")
Depending on your JDK used for launching Eclipse, you might want to stick with Sun option -XX:MaxPermSize=512m
Even though those aren't the heap space parameters, they might influence how Eclipse runs.
This is the best configuration for Eclipse NEON and o.s. Windows 10 with 4GB of Ram:
-startup
plugins/org.eclipse.equinox.launcher_1.3.201.v20161025-1711.jar
–launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.401.v20161122-1740
-product
org.eclipse.epp.package.jee.product
–launcher.defaultAction
openFile
–launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
–launcher.XXMaxPermSize
256m
–launcher.defaultAction
openFile
-vm
C:/Program Files/Java/jdk1.8.0_121/bin/javaw.exe
–launcher.appendVmargs
-vmargs
-Dosgi.requiredJavaVersion=1.8
-Xms256m
-Xmx512m
-XX:PermSize=256m
-XX:MaxPermSize=512m
If you have 8GB of Ram modify -XX:PermSize=512m and -XX:MaxPermSize=1024m.
