'D'own: Watchdog terminated (due to scheduled or gracefull shutdown)

'C'anceled: Watchdog marked as terminated by other process as SYN record was not updated in time.

'B'locked: Watchdog is down but new session must not start (i.e. if a watchdog process finds during start a 'B'locked entry on it's node it will terminate immediately without creating a new SYN record)
