Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of distribution lists may be affected by this problem.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    When a client uses MQOPEN to open many queues in a distribution
    list then this may fail with an MQRC_CONNECTION_BROKEN return
    code and an rrcE_PROTOCOL_ERROR FDC with probe identifier
    RM680078 is generated on the server.
    
    The problem was caused by the queue manager's channel code using
    an incorrect variable in a data validation test when validating
    the data received from the client.
    

Problem conclusion

  • The queue manager channel code was corrected so that validation
    checks used the correct variable.
