    ****************************************************************
    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.
