  ****************************************************************
  The CICS DSRTPGM SIT parameter for a routing region specified
  EYU9XLOP as the distributed routing program.  The problem
  presented as an EYUWG0106E error within CPSM.  This indicated a
  shortage of 'Workload Manager, Managed Address Space List
  Elements' (WNLEs).  A task running on CICS was configured to run
  exit program EYU9XLOP at task end and had it done so, would
  have been routed to the CMAS and freed off any WNLEs.  DFHEIIC
  was driven and attempted to invoke exit EYU9XLOP in routine
  SHIP_ROUTABLE_START.  However, this failed due to a revoked
  userid.  As a consequence, EYU9XLOP was not called and WNLEs
  were not freed.  This occurred many times eventually causing an
  EYUWG0106E to be issued.

Problem conclusion

• Routine SHIP_ROUTABLE_START in DFHEIIC has been modified and
  if DYROPTER=Y, will now call link_dynamic_router to drive
  CPSM exit EYU9XLOP unconditionally.
