Increase heap size to your eclipse

Here is the example to specify the eclipse vm arguments in eclipse.ini file to avoid eclipse memory issues during your development.

-startup

plugins/org.eclipse.equinox.launcher_1.0.100.v20080501.jar

--launcher.library

plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.0.100.v20080428-1330

-showsplash

org.eclipse.platform

-vm

/usr/lib/jvm/java-1.5.0-sun/jre/bin/java

-vmargs

-Xms512m

-Xmx1024m

-XX:+UseParallelGC

-XX:PermSize=512M

-XX:MaxPermSize=1024M

If you are working with eclipse plug-in development, while launching your eclipse application you have to specify the vm arguments so that it will be available for your target platform as well.

Please find the screenshot below to configure it.
