    ****************************************************************
    Cluster cache queries are delayed in a sub optimal way for some
    environments when waiting for cluster maintenance to complete.
    
    This is caused by an delay in the code that suspends cluster
    cache queries by 1 second while cluster maintenance completes.
    

Problem conclusion

  • The ability to alter the default time that cluster cache queries
    wait for when cluster maintenance is in effect has been added.
    The default behavior is unchanged.
