Java.lang.OutOfMemoryError on Eclipse with FlexBuilder plugin

Question

Dear All,
I am compiling a J2EE+Flex application on eclipse ganymede Version: 3.4.1 with the following eclipse.ini settings. (I am working on windows7 machine with 2GB Ram)
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
512M
-framework
plugins\org.eclipse.osgi_3.4.2.R34x_v20080826-1230.jar
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms1024m
-Xmx1024m
-XX:PermSize=512m
-XX:MaxPermSize=512m
-XX:+HeapDumpOnOutOfMemoryError
-Djava.net.preferIPv4Stack=true
But I have continuously happened to face for the following Memory out of bounce exception during compiling the application.
An internal error occurred during: "Building Workspace". java.lang.OutOfMemoryError
Following is the exception trace at <workspace>/.metadeta/.log file.
eclipse.buildId=M20080911-1700

Someone please be kind enough to help me out to get rid of this exception, Sounds like the exception fired from the Flex compiler. I have been working on days in finding a solution for this. What I found in every place was asking to increase the memory for JVM, as you can see I have already done it at the eclipse.ini file, but the error popping up continuously.
Thanks a lot in advance

NoNick4Me,
Thanks for the reply... I tried with the following settings on the eclipse.ini
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256M
-framework
plugins\org.eclipse.osgi_3.4.2.R34x_v20080826-1230.jar
-vm
C:\Program Files\Java\jdk1.6.0_11\bin\javaw.exe
-vmargs
-Xms128m
-Xmx512m
-XX:PermSize=256m
-XX:MaxPermSize=512m
-Djava.net.preferIPv4Stack=true
and I cant see any diffferance of the result. I am still getting the same out of memory exception as mentioned above..
Please let me know your thouhts....
Thnkx
