You might want to look at replacing this with the expanded XML for a cluster setup. It's a lot more XML, but it gives you much more control over your configuration. See the following link which shows what the above element is equivalent to. https://tomcat.apache.org/tomcat-6.0-doc/cluster-howto.html#For_the_impatient Once you make the switch, you can try adjusting the "dropTime" and "frequency" settings like I mentioned in my previous email. You'd set them on the <Membership/> element. https://tomcat.apache.org/tomcat-6.0-doc/config/cluster-membership.html Dan > <Realm className="org.apache.catalina.realm.UserDatabaseRealm" > resourceName="UserDatabase"/> > <Host name="localhost" appBase="webapps" > unpackWARs="true" autoDeploy="true" > xmlValidation="false" xmlNamespaceAware="false"> > </Host> > </Engine> > </Service> > </Server> > > > >> If you suspect a network issue, you could try monitoring with Wireshark or >> tcpdump to capture the network packets.
