PM80350: The catalog server does not retry timed out, placement service work.

APAR status

• Closed as program error.

Error description

• The catalog server sends placement work to a container.  If the
  work does not complete in time or if the container server does
  not receive the work request, then the catalog server does not
  retry. This behavior stops the shard containers from being
  successfully placed and can lead to other errors in the
  data grid.
  
  In the catalog placement trace, workTimedout entries are
  displayed.

  *                      Scale processing can occur on           *

  ****************************************************************
  The processing needed in the catalog server to include a
  container for potential placement can be non-trivial.
  Therefore, as the number of containers in a domain increase,
  this processing can put a strain on the ORB thread pools.
  However, after the message is received in the catalog, the
  processing needed to include the given container for placement
  can occur on a separate thread.
  

Problem conclusion

• A fix is provided to offload the ORB thread and subsequently,
  run processing on a specific eXtreme Scale thread.
