  ****************************************************************
  A terminal session is lost while a RECEIVE is active to VTAM
  driving the CICS LOSTERM exit DFHZLTX and message DFHZC2410. One
  of the actions for MSGDFHZC2410 is ABRECV resulting in a RESETSR
  being issued to VTAM. The only valid action after LOSTERM is
  CLSDST so the RESETSR fails resulting in message DFHZC2467
  Invalid CID. The processing of MSGDFHZC2467 issues another
  RESETSR which again fails, leading to a loop of DFHZC2467
  and its associated action message DFHZC3437.

Problem conclusion

• If LOSTERM has been driven (and the Must CLSDST flag TCTECRQ
  set) then the CICS RESETR module DFHZRST has been changed to
  bypass RESETSR.
