Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of MQ .Net client application experiencing network issues
    
    Platforms affected:
    Windows
    
    ****************************************************************
    PROBLEM SUMMARY:
    While sending data through the socket, if some network related
    issues are encountered, the MQ .Net Client code passes a system
    socket exception to the application instead of an MQ Exception.
    

Problem conclusion

  • WebSphere MQ code is modified such that MQRC_CONNECTION_BROKEN
    error is now thrown (instead of socket exception) in case of a
    network issue, while sending data through socket.
