  * RECOMMENDATION:                                              *
  ****************************************************************
  When CICS TG sends channel and container data to CICS over the
  IPIC protocol, the data is split into 60k chunks. Some data
  must not be split across two chunks, however, in some situations
  CICS TG incorrectly splits data and sends it to CICS. Reading
  the incorrectly split data causes the reported CICS errors. The
  transaction is abended in CICS with abend code AITJ. The client
  application might become unresponsive.
  

Problem conclusion

• CICS Transaction Gateway has been changed to rectify the error.
