Error description

  • A timing issue can cause a Servers Stats TCA to hang when the
    Manager is shutdown.  The Manager will now inform the Servers
    that it is shutting down in an attempt to resolve the timing
    issue.  The Servers will now ignore the invalid GFCB causing the
    U3099.  This also fixes a problem where a Standby Server can
    attempt to take-over while the main Server is still active.
