java.lang.OutOfMemoryError: PermGen space with eclipse

By default, Eclipse comes with below PermGen configuration in eclipse.ini file.
--launcher.XXMaxPermSize
256m

But this is not working with some versions. As per eclipse bug, this is not working with Java 1.6_21, but I was facing this issue even in Java 1.6_32 as well.

Anyway,add below parameter in eclipse.ini as a vm argument to resolve the issue.
-XX:MaxPermSize=256M

Even after this, if your eclipse is crashing with PermGen space issue, then try to increase the size.
I would say 512M is a very big size for PermGen space, If some application is taking more than that means, it's a real application issue, developers need to analyze where it's taking so much of space.
