Setting JVM maxperm size outside of Eclipse.ini

I'm using eclipse64 3.7.1 with Linux RHEL5 64 I have 8gigs of ram.

No matter how large I set the 

-Dosgi.requiredJavaVersion=1.5
-XX:MaxPermSize=1024M
-Xms1024m
-Xmx1024m

I continue to get errors like:

Error while logging event loop exception:
java.lang.OutOfMemoryError: PermGen space
        at java.lang.ClassLoader.defineClass1(Native Method)
        at java.lang.ClassLoader.defineClass(ClassLoader.java:791)
        at org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader.

Is there anywhere else I can configure memory options that relate to eclipse and the JVM? Please help.

If you're getting that exception even after setting the max PermGen size to 1024M, it is likely that you have classloader leaks in your application. Increasing the PermGen size will mitigate these exceptions for a while but might not be very helpful for a long-running application.
