Problembeschreibung
Wenn Microsoft BitLocker Administration und Überwachung 2.5 Wiederherstellungsdatenbank viele Clients herstellen können SQL-Deadlocks in der Datenbank auftreten. Daher können Schlüssel von Helpdesk-Portal oder Self Service Portal wiederhergestellt werden. Neue Kunden erhalten Fehlermeldungen beim Verschlüsseln der MBAM-Dienst nicht mehr erreichbar ist. Dies bewirkt, dass Timeouts und andere Fehler.
Darüber hinaus die folgenden treten MBAM svc-Ablaufverfolgungsprotokolle c:\inetpub\Microsoft BitLocker Management Solution\Logs\Recovery und Hardware dienstjahres * .svclogs:
Transaktion (Prozess-ID 63) wurde auf einen anderen Prozess blockiert und wurde als Deadlockopfer ausgewählt. Führen Sie die Transaktion erneut aus. Uncommittable Buchung wird am Ende des Stapels erkannt. Die Transaktion wird ein Rollback ausgeführt.
Problemlösung
Aktualisieren Sie zur Behebung des Problems die gespeicherten Prozeduren der Wiederherstellungsdatenbank MBAM zugeordnet. Führen Sie hierzu die folgende Transact-SQL-Skripts:
