  * PROBLEM DESCRIPTION:                                         *
  * Sysplex Monitoring recognized that                           *
  * OMPROUTE was not responsive and                              *
  * removed the stack from the Sysplex.                          *
  ****************************************************************
  * RECOMMENDATION:                                              *
  * Apply PTF                                                    *
  ****************************************************************
  A thread reading the routing table
  ended with a non-retryable abend. This
  causes all later attempts to update the
  routing table to hang. If OMPROUTE is
  being used OMPROUTE will also hang
  when it attempts to update the routing
  table. If OMPROUTE is hung and Sysplex
  Monitoring is being used, then Sysplex
  Monitoring will recognize the OMPROUTE
  hang and leave the sysplex.

Problem conclusion

• The stack recovery code was changed to recognize when a
  non-retryable abend occrs while reading the routing table.
  In this case the recovery code will now correctly clean up
  the routing table to allow updates.
