java.lang.OutOfMemoryError: PermGen space

[Bruce Wayne]

Hello,

I am running Red Hat Linux 2.6.18-164.el5 #1 SMP  x86_64 x86_64 x86_64
GNU/Linux with Tomcat 6 as seen below:

# /opt/tomcat/bin/version.sh

My JAVA_OPTS are:
JAVA_OPTS="$JAVA_OPTS -Djava.awt.headless=true -Dfile.encoding=UTF-8 -server

-XX:PermSize=1024m -XX:MaxPermSize=1024m -XX:+DisableExplicitGC"

My system has 6GB of RAM.

I keep getting the following error:
