Session replication fails on ReplicationValve invocation
Hi,
I'm currently trying to establish a cluster of tomcat 5.5.27 servers to deploy sakai in, so I'm stuck on version 5.5. It is not an option to upgrade to tomcat 6 which from all accounts has much better session replication.
I have cluster membership up and working via multicast and the two nodes add each other as replication targets. When I try to establish a connection to the server from my web browser to the default port of 8080 I get this neat error in my catalina.out:
ERROR: An exception or error occurred in the container during the request processing (2009-06-17 16:43:49,545 http-172.31.3.37-8080-Processor5_org.apache.catalina.connector.CoyoteAdapter)
java.lang.NullPointerException
at org.apache.catalina.cluster.tcp.ReplicationValve.invoke(ReplicationValve.java:348)
I'll put full errors and configs at the bottom of the email. The errors occurs regardless of whether I access an empty/nonexistent context or the servlet-examples which are currently installed.
The servers are multi homed with 3 interfaces. Eth0 is the primary public interface, eth1 is my iSCSI network and eth2 is the backend cluster network. All neatly VLANd from each other in seperate subnets. Multicast membership works, I can see the packets arriving via tcpdump and the membership propagation is occurring.
I have tried binding the receivers to both public and private interfaces but have had no luck. The receivers are up and appear to be functional. I can telnet to them and when I enter gibberish into the console it tell me I am sending malformed headers.
By using tcpdump and netstat I can see that neither tomcat instance is originating a sender session to connect to the other servers receiver.
I have tried fastsyncqueue and pooled style senders from the documentation. Currently configured for pooled as it looked the simpler config to diagnose. jvmRoute is configured via -D options passed to java as a lot of our configs are done dynamically so as to have a single server.xml across the cluster environments. We have a shared disk backend system to enable this.
Any suggestions for diagnosis, help, fixes or otherwise would be very much appreciated.
Regards,
Dave

Posted by Lingagiri <vi...@chase.com>.
How did you monitored that "cluster membership up and working via multicast
and the two nodes add each other as replication targets."

All requests are handled by /some/ context. If the URL doesn't match any
context, it will be handled by the ROOT context. If no ROOT context is
deployed, Tomcat will give you a Bad Request response code (IIRC).

I think I may have sorted the problem. Would that have occurred if I was asking for a webpage without a context? i.e. just hitting some undefined area?
Thanks,

Hello Dave
that line from ReplicationManager is getManager()
Manager manager = request.getContext().getManager();
i would check to make sure the Manager node in /context.xml
<!-- The contents of this file will be loaded for each web application -->
<Context>
<!-- Default set of monitored resources -->
<WatchedResource>WEB-INF/web.xml</WatchedResource>
<!-- Uncomment this to disable session persistence across Tomcat restarts -->
<Manager pathname="/" />
<!-- Uncomment this to enable Comet connection tacking (provides events
