  *                      an APPL, RCPSRLBP, pointed to freed     *

  * RECOMMENDATION:                                              *
  ****************************************************************
  If an APPL defaults to or is defined with REGISTER=CDSERVR (or
  defined with REGISTER=NETSRVR on an end node), it is added to
  a registration list in the RDTE representing the APPL major
  node when the APPL is activated. These APPLs are then
  registered to the Directory Services database - the central
  directory server in the case of APPLs on a network node, or the
  network node server in the case of APPLs on an end node.
  
  However, when an APPL is deleted from the application major
  node with VARY ACT,ID=appl_majnode,UPDATE=ALL the storage is
  freed without removing it from the registration list. This
  can result in abends when attempting to access an APPL via
  the registration list.
  
  NOTE: Changing the name of an APPL is the equivalent of adding
        an APPL with the new name and deleting the APPL with the
        old name, so this problem can also occur with a name
        change.
  

Problem conclusion

• Module ISTSDCLL is changed to delete the directory services
  registration and remove an APPL from the registration list
  when it is deleted with VARY ACT,UPDATE=ALL.
