  DFHAP0001 applid
  An abend (code 0C4/AKEA) has occurred at offset X'00000822' in
  module DFHZNAC
  .
  The cause of the 0C4 is that field TCTVSRQ is
  00000000 . It should always be either the address of a TCTTE or
  FFFFFFFF .
  .
  You also notice that there is more than 1 CSNE
  task active .

  Earlier in this run of CICS a CSNE transaction
  got abendAXSB in program DFHXMAB . Here is an example of
  that:
