In SQL Server 2008 R2 wurden mehrere Deadlock-Berichte mit dem Kennwort "* password ------------" im Eingabepuffer angezeigt. Es sieht aus wie ein Angriff, aber in diesem Fall kenne ich den Grund oder die Art des Angriffs nicht.
(Das Protokoll wurde von einem erfahrenen DBA erstellt, der viel Erfahrung hat und mir das sagte, nicht mir)
Weiß jemand was es ist? Vielen Dank!
