Default Clustering tomcat

Hi,

I'm having some difficulty getting a tomcat cluster service up and running with Centos v6.2 and Tomcat6.

The service won't start tomcat and it keeps ping-ponging back and forth between the servers every 30 seconds.

Below is the cluster.conf file, "messages" file and the rgmanager.log

Any help would be appreciated.

Thanks,
-Bill


Here's my cluster.conf
---------------------------

<?xml version="1.0"?>
<cluster config_version="11" name="AUTHCLUSTERDEV">
<cman expected_votes="1" two_node="1"/>
<clusternodes>
<clusternode name="AUTHCLUSTER1DEV" nodeid="1">
<fence>
<method name="single"/>
</fence>
</clusternode>
<clusternode name="AUTHCLUSTER2DEV" nodeid="2">
<fence>
<method name="single"/>
</fence>
</clusternode>
</clusternodes>
<rm>
<failoverdomains>
<failoverdomain name="failoverDom" nofailback="1" ordered="0" restricted="0">
<failoverdomainnode name="AUTHCLUSTER1DEV" priority="1"/>
<failoverdomainnode name="AUTHCLUSTER2DEV" priority="1"/>
</failoverdomain>
</failoverdomains>
<resources>
<ip address="172.16.223.69" monitor_link="1"/>
<tomcat-6 config_file="/etc/tomcat6/tomcat6.conf" name="tomcat6" shutdown_wait="30"/>
</resources>
<service domain="failoverDom" name="ipservice" recovery="relocate">
<ip ref="172.16.223.69">
<tomcat-6 ref="tomcat6"/>
</ip>
</service>
</rm>
<logging debug="on"/>
</cluster>

Here's the "messages" file after one full cycle of ping-pongs
