  A CICS client sends a DPL request over IPIC to a CICS server
  with large container. After CICS server processes the request it
  sends response to CICS client with large container. DFHISZA is
  invoked to send the container data in buffer to CICS client.
  As the container data is very large, more than 1 buffer is used
  to send the IS field for container data. Buffers are in a chain.
  Unfortunately, the data of buffer in the middle of the chain
  is corrupted. When DFHISZA tries to write a trace entry for
  the buffer it wrongly treats the corrupted buffer data as a new
  IS field. As a result, it wrongly calculate the length of the
  IS field and finally points to an address beyond the buffer.
  Finally abend AKEA occurs.
  

Problem conclusion

• DFHISZA has been changed to validate that the data to be traced
  does not exceed the end of the buffer before write a trace
  entry.
