CRM 4.0 SQL Time out Issue

We recently started getting problem while creating new entity or importing any new entity in one of our CRM Environment.

Following is full description of error logged on Server Event Log.


The description for Event ID 17415 from source MSCRMAsyncService cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.
If the event originated on another computer, the display information had to be saved with the event.
The following information was included with the event:
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.SqlConnection.OnError(SqlException exception, Boolean breakConnection)
at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj)
at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj)

at System.Data.SqlClient.SqlDataReader.get_MetaData()
at System.Data.SqlClient.SqlCommand.FinishExecuteReader(SqlDataReader ds, RunBehavior runBehavior, String resetOptionsString)
at System.Data.SqlClient.SqlCommand.RunExecuteReaderTds(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, Boolean async)
at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method, DbAsyncResult result)
at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method)
at System.Data.SqlClient.SqlCommand.ExecuteReader(CommandBehavior behavior, String method)
at System.Data.SqlClient.SqlCommand.ExecuteDbDataReader(CommandBehavior behavior)
at System.Data.Common.DbCommand.System.Data.IDbCommand.ExecuteReader()
at Microsoft.Crm.CrmDbConnection.InternalExecuteReader(IDbCommand command)
at Microsoft.Crm.CrmDbConnection.ExecuteReader(IDbCommand command, Boolean impersonate)
at Microsoft.Crm.Asynchronous.DataAccessBase.ExecuteSqlCommandAndProcessRecords(IDbCommand command, RecordProcessor recordProcessor)
at Microsoft.Crm.Workflow.WaitSubscriptionDataAccess.Notify(IDbCommand selectCommand, WaitNotificationService waitNotificationService)
at Microsoft.Crm.Workflow.WaitSubscriptionDataAccess.Notify(String hostId, WaitNotificationService waitNotificationService, Int32 maxRetries)
at Microsoft.Crm.Workflow.WorkflowHost.OnNotificationTimerEvent(Object sender, ElapsedEventArgs e)
the message resource is present but the message is not found in the string/message table

There is a slow response from SQL which leads to the CRM platform timing out.


After carefully debugging and investigating it turns to be SQL Time out issue and the process of creating new entity is taking more than 30 seconds.
We added following registry keys to HKLM\Sofware\Microsoft\MSCRM folder and this resolved this problem.

DWORD OLEDBTimeout = 300000 (decimal)
DWORD ExtendedTimeout = 1000000 (decimal)
DWORD NormalTimeout = 1000000 (decimal)
