Hello together, I am using to Tomcat 5.5.26 Servers. I took over the responsibility for this system some time ago. Since then we already got the following error message.
SEVERE: Manager [/mywebapp]: Unable to receive message through TCP channel java.lang.ClassNotFoundException: After questioning what this error is about I got no response but the comment that everything is running fine. So I haven't searhc after it. But now after having a rollout of new servlet version we have some serious performance issues. And now I have to check for every severe error message I can find. But unfornatly I haven't found a solution or cause for this. The only thing which I have found is a posting that this might be a problem of the tomcats version and that this might be a bug which was solved in 5.5.28. Is this correct? The cluster configuration part in server.xml looks like a standard configuration: <Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false"> <Cluster className="org.apache.catalina.cluster.tcp.SimpleTcpCluster" managerClassName="org.apache.catalina.cluster.session.DeltaManager" expireSessionsOnShutdown="false" useDirtyFlag="true" notifyListenersOnReplication="true"> <Membership className="org.apache.catalina.cluster.mcast.McastService" mcastAddr="228.0.0.4" mcastPort="45564" mcastFrequency="500" mcastDropTime="3000"/> <Receiver className="org.apache.catalina.cluster.tcp.ReplicationListener" tcpListenAddress="auto" tcpListenPort="4002" tcpSelectorTimeout="100" tcpThreadCount="6"/> <Sender className="org.apache.catalina.cluster.tcp.ReplicationTransmitter" replicationMode="pooled" ackTimeout="15000"/> <Valve className="org.apache.catalina.cluster.tcp.ReplicationValve" filter=".*\.gif;.*\.js;.*\.jpg;.*\.png;.*\.css;.*\.txt;"/> <Deployer className="org.apache.catalina.cluster.deploy.FarmWarDeployer" tempDir="/tmp/war-temp/" deployDir="/tmp/war-deploy/" watchDir="/tmp/war-listen/" watchEnabled="false"/> <ClusterListener className="org.apache.catalina.cluster.session.ClusterSessionListener"/> </Cluster> I found out thatwe are not using the Deployer context. It is just configured, but both Tomcats servers use a deployment path on its local storage. Has somebody an idea?
