my only experience with Redhat 9 is that it doesn't play well with NIO.
I have not successfully ran tomcat clustering on RH9, I use RH8.
I also don't have a RH9 machine at home yet, so I can't develop for it

100% cpu can mean that you have a multicast problem, try to run
java -cp tomcat-replication.jar MCaster
download the jar from http://cvs.apache.org/~fhanik/
