  * PROBLEM DESCRIPTION:                                         *
  * A 4C5 abend occurs in EZBPFSEL because the token passed by   *
  * the LFS does not match the token in the socket control block *
  * (SCB).                                                       *
  ****************************************************************

  * Apply the PTF                                                *
  ****************************************************************
  The PFS can incorrectly free a socket control block if an AT-TLS
  connection has not finished the TLS handshake when the socket
  close is issued. This later leads to the 4C5 abends in the PFS
  layer. The 4C5 abend can also occur in other PFS parts.
  

Problem conclusion

• The interface between the PFS layer and the TCP/IP stack is
  updated to insure that the socket control block is freed
  correctly.
