Context reload causes ClusterManager to stop operating

           Summary: Context reload causes ClusterManager to stop operating
           Product: Tomcat 5
           Version: 5.0.28
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: Major
          Priority: Other
         Component: Catalina:Cluster
        AssignedTo: [EMAIL PROTECTED]
        ReportedBy: [EMAIL PROTECTED]


A functioning clustered application works fine when the tomcat server is
initially started.  Sessions are replicated, etc.

As soon as the context is reloaded on one server, the sessions are no longer
replicated between servers.  A full tomcat restart is required to restore this
functionality.

The application and configuration are known to be functional, and the problem
does not occur on 5.0.25.  The problem only occurs on our 5.0.28 installation. 
We have downgraded our installation to verify this, and the same functionality
that does not work properly on 5.0.28 does in fact work on 5.0.25.

There is a thread with the subject of "Clustering and session replication" in
the tomcat-users mailing list, starting on 9/29/2004.

All relevant output is below:
