  ****************************************************************
  Intelligent Management enabled web servers return 404 error
  codes for requests destined for static clusters due to an
  error/window in the Intelligent Management REST service that
  prevents proper routing information from being returned to the
  web servers about the static cluster definition. The
  error/window presents itself when the Intelligent Management
  REST service is serving a delta response back to the web
  server and a change has occurred in the On-Demand
  Configuration data that causes the web servers interest in the
  static cluster to change.
  

Problem conclusion

• The Intelligent Management REST service has been altered such
  that it recognizes when a web server's interest in an existing
  On-Demand Configuration object has changed while the service
  is attempting to serve a delta response. The response is then
  altered to include all relevant objects in-relation to that
  interest change, ensuring complete and proper routing
  information is delivered to the web server.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.5.2.  Please refer to the Recommended Updates
