Eclipse:java.lang.OutOfMemoryError: PermGen space

Question

My eclipse configuration.

Eclipse : latest version (Kepler)

My eclipse config.ini

-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20130327-1440.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.200.v20130521-0416
-product
org.eclipse.epp.package.standard.product
--launcher.defaultAction
openFile
-showsplash
org.eclipse.platform
--launcher.defaultAction
openFile
--launcher.appendVmargs
-vmargs
-Dosgi.requiredJavaVersion=1.6
-Xms40M
-Xmx512M

After Updation From to Juno to Kepler.But with the same configuration I did'nt face any issue.

Exception I'm facing is

      [ERROR] Out of memory; to increase the amount of memory, use the -Xmx flag at startup (java -Xmx128M ...)

It's keep telling me

[ERROR] Out of memory; to increase the amount of memory, use the -Xmx flag at startup (java -Xmx128M ...)

Here is my VM args

What could be the issue..

Thanks for any help.

From Eclipse wiki-

Why am I getting a java.lang.OutOfMemoryError: PermGen space?

The default maximum Permanent Generation space set by your JRE may be too small. This is unrelated to the maximum allowed Heap space. You can increase the maximum PermGen size by launching Eclipse with the VM argument: -XX:MaxPermSize=128m
