Mod_JK + Tomcat Replication Problem

[schoysi]

Hallo liebe Tomcat Freunde,

ich habe ein Problem mit dem Aufbau eines Tomcat Clusters welcher über Apache + Mod_JK gebalanced wird (Debian Lenny) Tomcat: 6.0.26 und hoffe dass mir hier jemand weiterhelfen kann:

Problem:
Seitenaufruf auf TomcatServer1 wird von TomcatServer2 verarbeitet und Seitenaufruf auf TomcatServer2 wird von TomcatServer1 verarbeitet.

Dabei taucht folgende Meldung im catalina.out des jeweils (nicht arbeiteten) Servers auf:

Apr 28, 2010 3:51:00 PM org.apache.catalina.ha.session.DeltaManager messageReceived

Die Cluster Konfiguration wurde nach der offiziellen ClusterHowTo vorgenommen http://tomcat.apache.org/tomcat-6.0-...ter-howto.html

Meine workers.properties sieht wie folgt aus:

workers.tomcat_home=/opt/tomcat-6.0.26
workers.java_home=/usr/lib/jvm/java-6-sun
ps=/

worker.list = bal1,stat1

worker.server1.type = ajp13
worker.server1.host = 10.10.1.1
worker.server1.port = 8009
worker.server1.lbfactor = 10

worker.server2.type = ajp13
worker.server2.host = 10.10.1.2
worker.server2.port = 8009
worker.server2.lbfactor = 10

worker.bal1.type = lb
worker.bal1.sticky_session = 1
worker.bal1.balanced_workers = server1,server2
worker.stat1.type = status
worker.bal1.local_worker_only=1

Clusterteil der Server.xml:

Ich hoffe jemand hat eine Idee und kann mir weiterhelfen. Stehe momentan echt an.

Danke
