    You have to increase your memmory setting for eclipse. There are two ways.

    1)Add extra JVM parameters while calling eclipse
    2)Edit eclipse.ini. In this approach don’t need to pass parameters

    Open your eclipse.ini which can be found in eclipse install directory. Modify the -xmx to a higher value.

    eg

    -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=256M
-XX:MaxPermSize=512M
