    Within the data blocks of the FDC record, there are references
    to an EFAULT signal ("Bad address") being returned by the
    operating system.
    

Local fix

  • Change the application or queue manager configuration to use
    shared bindings
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This issue affects users of MQ applications which connect using
    isolated bindings and perform MQPUT
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    A programming error meant that when passing an MQPUT request
    from an MQ application to the queue manager using isolated
    bindings, it was possible for uninitialized data to be passed to
    the operating system. If this uninitialized data was non-null,
    EFAULT was returned by the OS.
    

Problem conclusion

  • The MQ isolated bindings logic, used by isolated bindings
    applications and the queue manager, has been corrected to
    prevent this use of uninitialized data.
