    This problem occurs when servers are added to the cluster@port
    combination AFTER rules have been added for the cluster@port.
    

Problem conclusion

  • Rules and servers are stored based upon the cluster@port
    combination. The manager attempts to obtain the servers from
    the cluster@port to compute the weights but expects the
    servers to be ordered before the rules.  Code corrected to
    remove this assumption.
    
    Fix applies to all operating systems. Fix can be avoided by
    adding servers to the cluster@port before adding rules for the
    cluster@port.
    
    Fix level:
       8.5.5.18
       9.0.5.4
    

Temporary fix

  • Fix can be avoided by
    adding servers to the cluster@port before adding rules for the
    cluster@port.
