Thanks for the article Dion - it explains the situation beautifully. I've been suffering with the same issue for a while and the resolution was to increase the MaxPermSize as describe by Renier: *XX:MaxPermSize=128M. It's nice now to know what causes the problem.
I've had to increase the MaxPermSize for our production Tomcat and JBoss servers (never Eclipse though, since Tomcat runs in it's own JVM).
