Symptômes
Lorsque de nombreux clients se connectent aux bases de données récupération Microsoft BitLocker Administration et surveillance de 2,5, des blocages SQL peuvent se produire dans la base de données. Ainsi, les clés ne peut pas être récupérées à partir du portail de support technique ou le Self Service Portal. Nouveaux clients reçoivent des erreurs lorsqu’ils tentent de crypter que le service MBAM devient inaccessible. Cela provoque des délais d’attente et d’autres erreurs.
En outre, les erreurs suivantes se produisent dans les journaux de suivi MBAM svc sous c:\inetpub\Microsoft Solution\Logs\Recovery de gestion BitLocker et matériel Service\ * .svclogs :
Transaction (63 d’ID de processus) a été bloquée sur les ressources avec un autre processus et a été choisie comme victime du blocage. Réexécutez la transaction. Transaction uncommittable est détectée à la fin du lot. La transaction est restaurée.
Résolution
Pour résoudre ce problème, mettez à jour les procédures stockées associées à la base de données de récupération MBAM. Pour ce faire, exécutez les scripts Transact-SQL suivantes :
