Error description

  • UMS is incorrectly flagging certain accelerator tables with a
    warning that statistics have not been collected after loading,
    even when statistics were successfully collected during the load
    process. This occurs when the last load time and last statistics
    collection time have identical timestamps. Instead of
    interpreting this as valid (statistics collected as part of the
    load), UMS treats it as a missing statistics scenario and
    displays a yellow warning triangle with the tooltip: Statistics
    not yet collected after loading. This results in a misleading
    warning for users, despite no actual issue with the tables
    statistics.
