   This issue has been fixed in ISTFSVEF and has been increased to the lastPort number before searching for available ports.This reduces the likelihood that the last interface issuedas soon as it is reissued.ISTFSVPC was changed to free up the last allocated slot whenAttach port numbers.This is dolwives be a logical route from OA19741.
