我们的系统中有这个问题。我们正在使用System.Transactions和合作TransactionScope（在这种情况下，大多数情况下，绝对是）。我们刚刚迁移EnterpriseServices到SystemTransactions最近，在繁重的多线程工作期间，我们多次收到此错误：
System.Transactions.TransactionInDoubtException: The transaction is in doubt. ---> System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning() at System.Data.SqlClient.TdsParserStateObject.ReadSniError(TdsParserStateObject stateObj, UInt32 error) at System.Data.SqlClient.TdsParserStateObject.ReadSni(DbAsyncResult asyncResult, TdsParserStateObject stateObj) at System.Data.SqlClient.TdsParserStateObject.ReadNetworkPacket() at System.Data.SqlClient.TdsParserStateObject.ReadByte() at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj) at System.Data.SqlClient.TdsParser.TdsExecuteTransactionManagerRequest(Byte[] buffer, TransactionManagerRequestType request, String transactionName, TransactionManagerIsolationLevel isoLevel, Int32 timeout, SqlInternalTransaction transaction, TdsParserStateObject stateObj, Boolean isDelegateControlRequest) at System.Data.SqlClient.SqlInternalConnectionTds.ExecuteTransactionYukon(TransactionRequest transactionRequest, String transactionName, IsolationLevel iso, SqlInternalTransaction internalTransaction, Boolean isDelegateControlRequest) at System.Data.SqlClient.SqlDelegatedTransaction.SinglePhaseCommit(SinglePhaseEnlistment enlistment)
它显然是在Scope.Complete().
我已经阅读了一些关于 的内容TransactionInDoubt，它可能发生在升级到 的过程中DTC，并且 SQL 或 MSDTC 可能存在轻微的连接问题。但是然后- Timeout Expired 是什么SqlException？超时到底在哪里？在提交？？？
在过去的几天里，我一直在扫描网络，并且到处都出现了一些情况，但没有好的答案。
帮助任何人？？
