I have had this problem in the past. I fixed it by addind a PermSize and MaxPermSize to my Java Opts in $JAVA_HOME/bin/run.conf Also see the wiki reference for more information on this. http://wiki.jboss.org/wiki/Wiki.jsp?page=OutOfMemoryExceptionWhenRedeploying <snip - from my run.conf> # Added the PermSize and MaxPermSize to fix the java.lang.OutOfMemoryError: PermGen space error # see: http://wiki.jboss.org/wiki/Wiki.jsp?page=OutOfMemoryExceptionWhenRedeploying JAVA_OPTS="$JAVA_OPTS -XX:NewSize=128m -XX:MaxNewSize=384m -XX:PermSize=128m -XX:MaxPermSize=128m -Xmx512m -Xms512m -XX:+DisableExplicitGC" HTH.
