Azure sql database Azure:连接超时已过期。登录后阶段经过的超时时间

今天早上我们在几百次以下得到了错误：

System.Data.SqlClient.SqlException (0x80131904): Connection Timeout Expired.  The   timeout period elapsed during the post-login phase.  The connection could have timed out while waiting for server to complete the login process and respond; Or it could have timed out while attempting to create multiple active connections.  The duration spent while attempting to connect to this server was - [Pre-Login] initialization=1; handshake=14; [Login] initialization=0; authentication=0; [Post-Login] complete=14008;  ---> System.ComponentModel.Win32Exception (0x80004005): The wait operation timed out

at System.Data.SqlClient.TdsParser.TryRun(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj, Boolean& dataReady)

我们怎么会暂停？当我们使用ManagementStudio进行连接时，会发生此错误事件，而且通常速度非常慢

默认SQL超时为15秒。我们应该把它设为120秒吗？在我看来，这就像Azure中的性能问题

有什么想法吗

谢谢

您是否都知道原因？这只是在登录时发生的吗？
