The other problem is that the xinetd package is buggy. it does not handle a TCP service of type WAIT properly. A fix is available at ftp://ftp.solucorp.qc.ca/pub/misc . Pick the file xinetd-18.104.22.168pre11-1wait.i386.rpm.
This update is based on RedHat own update. If you find something newer on RedHat site, pick it.
Then after installing the update, restart the service
rpm -Uvh xinetd-22.214.171.124pre11-1wait.i386.rpm /etc/rc.d/init.d/xinetd restart
