  ****************************************************************
  Large amounts of data sent over the sysplex LINK connection
  between ISM nodes (>61K) can cause the LINK connection to fail.
  Data larger than 61K is split into two parts when sent. The
  receiving node is not correctly joining these parts back
  together especially if they arrive in a different order to that
  sent; a quirk of Sysplex messaging.
  

Problem conclusion

• The code has been modified to cope with the above situations.
