Issue

We have 2 HornetQ nodes in cluster mode. When the server start, we have the following error :

Caused by: org.jboss.msc.service.DuplicateServiceException: Service jboss.naming.context.java.jboss.exported.NoPrefetchConnectionFactory is already registered

We noticed that the connection factory is duplicated in the standalone.xml :

                   <connection-factory name="RemoteConnectionFactory">
                        <connectors>
                            <connector-ref connector-name="netty"/>
                        </connectors>
                        <entries>
                            <entry name="java:jboss/exported/jms/RemoteConnectionFactory"/>
                            <entry name="java:jboss/exported/RemoteConnectionFactory"/>
                            <entry name="java:jboss/exported/NoPrefetchConnectionFactory"/>
                            <entry name="java:jboss/exported/jms/NoPrefetchConnectionFactory"/>
                        </entries>
                        <retry-interval>1000</retry-interval>
                        <retry-interval-multiplier>1.5</retry-interval-multiplier>
                        <max-retry-interval>60000</max-retry-interval>
                        <reconnect-attempts>1000</reconnect-attempts>
                    </connection-factory>
                    <connection-factory name="NoPrefetchConnectionFactory">
                        <connectors>
                            <connector-ref connector-name="netty"/>
                        </connectors>
                        <entries>
                            <entry name="java:jboss/exported/NoPrefetchConnectionFactory"/>
                        </entries>
                        <consumer-window-size>0</consumer-window-size>
                    </connection-factory> 

Can you please tell us how it can be duplicated in this file and what is the good configuration ?
