        ###@###.### 2005-1-06 03:25:59 GMT

        I am changing this bug's synopsis from:
        CMS-concurrent-sweep messages missing from a "normal" concurrent CMS cycle
        to:
        CMS: concurrent mode failures running S1AS at NCS installation
        to track the main nature of the current investigation.
        The secondary issue of explicating the verbose gc messages
        regarding occurance of a concurrent mode failure will also
        be tackled as part of this investigation, but is not the
        main thrust of thos bug.
        ###@###.### 2005-1-12 23:25:10 GMT

        I am changing this bug's synopsis (yet again),
        based on the current status of this engagement, from:

        CMS: concurrent mode failures running S1AS at NCS installation

        to

        CMS: more helpful message for concurrent mode failures
