%1 (%2) %3The database engine stopped.

The extensible storage engine database engine stopped.

Possible causes include:

• An online restoration failed. There may be missing log files on the computer or in an online restoration, or there may be old log files that are out of sequence with the log that is mentioned in the Restore.env file.
• A database could not be loaded. The directory where the database or logs exist might not have the correct permissions assigned to it in order to load the store.
• An information store was unloaded.
• There might be file-level virus-scanning software running against the log file directory.

To troubleshoot the problem, check the Application log and the System log to determine the exact sequence of related events leading up to this event.
