Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• HNTE is not beeing freed
  An element address is obtained for a DLUS PU which is being
  activated. The PU dial processing fails. But the element address
  is not released when the PU returns to Conct state.  The element
  address can not be used until VTAM is recycled.

  Host Node Table element address are not released when
  to a DLUS PU which failed in the dial process. This
  could possibly lead to a depletion of element addressed
  in the host.  The RPR_DLS_SERVED bit for a DLUS PU
  was being reset to early during the processing of a
  link failure. This cause the DLUS process for releasing
  network addresses to be bypassed in final PU deactivation.
  

Problem conclusion

• Module ISTDECP3 has been changed to not reset the RPR_DLS_SERVED
  bit in the PU. This will allow ISTDECP4 to release the network
  address obtained for the DLUS PU.  After the address has been
  released the bit will be turned off.
  
  NOTE.  Apar OW34866 also corrects a network address problem
         for DLUS PUs.
