Error description

• You are receiving a series of DFHPI0001 An abend (code 0C4/AKEA)
  occurred at offset X'FFFF' in module DFHPIII. You have to
  recycle the region to recover it.
  The root cause of the problem is an overlay of the WSBIND file.
  The overlay is x'F0F0F0F0F0F0F0F0F0'.  This has corrupted the
  entry in the ICM for one of the elements. Whenever
  DFHPIII processes that field it will try to convert the data in
  the ICM using a conversion type of x'F0'.This is an unexpected
  type so DFHPIII reports the error. The first action is to write
  a PI 0F08 trace entry.  Data1 for that trace entry is the
  element name. This gets copied from the ICM, but the length is
  one of the fields overlaid and is passed to trace domain as
  x'F0F0'.This gets handled as a negative value so does not cause
  the normal overlength trace entry processing to take place.
  The final trace entry length is calculated as x'C2' and it is
  being written at x'48_00021E28'. The data for data1
  gets copied using a MVCL instruction. The 2 byte length in the
  trace entry is x'F0F0' but as this was a negative value the real
  MVCL tries to copy x'FFFFFFFFF0F0' bytes of data and the 0C4
  occurs.
  This apar is raised to correct DFHTRPX so that large halfword
  lengths get handled as positive values and correctly cause
  overlength trace entry exceptions instead of large data copies.

  In the reported problem, DFHPIII was being driven to convert
  application data into XML.  During this conversion, an 0C4
  occurred in trace module DFHTRPX and was caused by an overlay
  of the ICM ( internal commarea ) that DFHPIII parses as part
  of normal processing.
  
  This overlay caused a halfword signed ICM field ( name_len in
  V5.1 and de_name_len in V5.2 ) to contain x'F0F0' which when
  loaded into a register, caused the leftmost bit to get
  propagated so the register contained a value of FFFFF0F0.
  This was used as a length value for a MVCL instruction and
  caused a massive overlay in the CICS region.

Problem conclusion

• DFHPIDC has been modified so that name_len in V5.1 and
  de_name_len in V5.2 has been modified so that it is now an
  unsigned field.  This will preclude bit propagation when it
  is loaded into a register.
