Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of IBM Session Manager V3.         *
  ****************************************************************
  * PROBLEM DESCRIPTION: Depending on TELNET parameters,         *
  *                      terminal can reconnect before Standby   *
  *                      is aware that Instance has died.        *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  ISZ0071E LU I029545 CLSDST error, RC=4, SC=16
  With Telnet parameters SHAREACB and LUSESSIONPEND when an
  Instance is cancelled the Telnet terminal session does not end
  but is immediately passed to the Standby Instance. The terminal
  LOGON may be driven before XCF messages have arrived at the
  Standby Instance to notify it of the demise of the Instance.
  The terminal user is still deemed to be active at the Instance,
  and the terminal is therefore passed to the (failed) system
  which gives the CLSDST PASS error seen in the above message.
  After receipt of the CLSDST error, the Signon task incorrectly
  sends the SIGNON panel to the terminal.
  

Problem conclusion

• When a terminal is found to be active (in the User CF table),
  wait a short time before retrying the attempt to add to the User
  CF table. This enables processing of XCF notification messages
  regarding Instance failure.
