http://issues.apache.org/bugzilla/show_bug.cgi?id=32280 Summary: Problem clustering tomcat when a failed server is restarting Product: Tomcat 5 Version: 5.0.27 Platform: Sun OS/Version: Solaris Status: NEW Severity: critical Priority: P2 Component: Catalina:Cluster AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] CC: [EMAIL PROTECTED] the GenericPrincipal.getPassword() returns null that is why you get this error, you can open a bugzilla report so that we can track it Filip -----Message d'origine----- It fails when it tries to write the principal information to the stream. Since I don't know what version of tomcat you are using, I can't tell you exactly what went wrong. maybe something in the principal returns null Filip -----Message d'origine----- We have a cluster Tomcat composed of two servers (default configuration of the cluster is used). When the first server is stopped, the cluster continues to work fine (requests are handled by the server that is running). But when the stopped server is restarting we can see these exceptions. The server that handle the requests log this exception Server 02 10 nov. 2004 17:13:54 org.apache.catalina.cluster.tcp.SimpleTcpCluster memberAdded INFO: Replication member added:org.apache.catalina.cluster.mcast.McastMember [tcp://w.x.y.z:41001,w.x. y.z,41001, alive=35] 10 nov. 2004 17:13:54 org.apache.catalina.cluster.session.DeltaManager messageReceived GRAVE: Unable to receive message through TCP channel java.lang.NullPointerException at java.io.ObjectOutputStream$BlockDataOutputStream.getUTFLength (ObjectOutputSt ream.java:1898) at java.io.ObjectOutputStream$BlockDataOutputStream.writeUTF (ObjectOutputStream .java:1769) at java.io.ObjectOutputStream.writeUTF(ObjectOutputStream.java:787) at org.apache.catalina.cluster.session.SerializablePrincipal.writePrincipal(Ser ializablePrincipal.java:180) at org.apache.catalina.cluster.session.DeltaSession.writeObject (DeltaSession.ja va:1457) at org.apache.catalina.cluster.session.DeltaSession.writeObjectData (DeltaSessio n.java:930) at org.apache.catalina.cluster.session.DeltaManager.doUnload(DeltaManager.java: 539) at org.apache.catalina.cluster.session.DeltaManager.messageReceived (DeltaManage r.java:854) at org.apache.catalina.cluster.session.DeltaManager.messageDataReceived (DeltaMa nager.java:762) at org.apache.catalina.cluster.tcp.SimpleTcpCluster.messageDataReceived (SimpleT cpCluster.java:576) at org.apache.catalina.cluster.io.ObjectReader.execute(ObjectReader.java:70) at org.apache.catalina.cluster.tcp.TcpReplicationThread.drainChannel (TcpReplica tionThread.java:129) at org.apache.catalina.cluster.tcp.TcpReplicationThread.run (TcpReplicationThrea d.java:67) In the same time the server restarting logs this information. server 01 Creating ClusterManager for context /myapp using class org.apache.catalina.cluster.session.DeltaManager 10 nov. 2004 17:13:54 org.apache.catalina.cluster.session.DeltaManager start INFO: Starting clustering manager...:/myapp 10 nov. 2004 17:13:54 org.apache.catalina.cluster.session.DeltaManager start ATTENTION: Manager[/myapp], requesting session state from org.apache.catalina.cluster.mcast.McastMember[tcp://w.x.y.z:42001,w.x.y.z,42 001, alive=111640].
