добрый день.
есть синхронная группа AAG из двух серверов ms sql 2014. при высокой нагрузке на базу (операции импорта), получается вот такой Exception:
Jul 19 2016 12:43:20 PM / 1468914200
System.Data.Entity.Infrastructure.CommitFailedException
An error was reported while committing a database transaction but it could not be determined whether the transaction succeeded or failed on the database server. See the inner exception and http://go.microsoft.com/fwlink/?LinkId=313468 for more information.
System.Data.Entity.Infrastructure.CommitFailedException: An error was reported while committing a database transaction but it could not be determined whether the transaction succeeded or failed on the database server. See the inner exception and http://go.microsoft.com/fwlink/?LinkId=313468 for more information. ---> System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. ---> System.ComponentModel.Win32Exception: The wait operation timed out

at System.Data.SqlClient.SqlInternalTransaction.Commit()
at System.Data.SqlClient.SqlTransaction.Commit()
....
хотелось бы работать в режиме транзакционной целостности, "could not be determined whether the transaction succeeded or failed" не очень устраивает.
есть идеи на этот счет ?
