Timeout during heavy loaded tasks on CRM 4

I beleived most of us faced the problem where you can not change business unit of a user in CRM 4 or MSCRMSynchronous seems unabled to delete huge data. If you use CRM diagnostic tool to debug the request step by step, you will found it is cause by the timeout issue.

Default CRM4 application configure OLEDB timout as 30 seconds. We can modify the register in application server to extend the time. Refer the screen capture below:-

We just need to extend the OLEDBTimeout value and add a new DWORD key "ExtendedTimeout" . You can create the 2 keys if does not exist. By right OLEDBTimeout is already inserted during installation.

  1. Run >regedit
  2. expand the tree to >HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSCRM
  3. Change the default value 30 on OLEDBTimeout to the seconds you prefer. (Modify by Decimal)
  4. Next, right click MSCRM, NEW DWORD rename to "ExtendedTimeout". (Modify the Decimal value to 1000000)
  5. Important: in Decimal value do not type value larger than 2,147,483,647
  6. After you successful run those 'resources hungry' tasks, set back to original value. Delte those key that previously does not exist.
Below is the exception I get in the event logs before I extend the timeout value.
Happy CRM'ing :D

Event Source: MSCRMAsyncService
Event ID : 17415

Exception: System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

Refer the Microsoft KB article also: http://support.microsoft.com/kb/918609


  1. We are looing at the same error, but appears that something other than load is causing this problem.

    We tried your fix, and the service remains in an active state that caused performance issues on server.

    We would love to know how you debuged the cause?

  2. I used CRm Diagnostic Tools 4 to debug CRM, you can get it from


    Additional things to check on your CRM asynchorounos.Used this query statement in MSCRM config DB

    select NVarCharColumn,ColumnName from DeploymentProperties
    where ColumnName in ('AsyncSdkRootDomain','ADSdkRootDomain','ADWebApplicationRootDomain' )

    make sure 3 of the NVarCharColumn is like[server:port]

    This solution worked for following error when publishing customization in a VPC

    Trace Info: [SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

    Thanks and keep up the good work


  4. thanks for your comment>FP

  5. This solution also worked for my CRM Advanced Find timeout issues that has made me resort to writing SQL queries to get the data I need out of CRM.

    Many thanks for posting this.

  6. kindly help
    this didn't solve my probelm at all

  7. ok.Can you elaborate more on the error you encounter?
    you can't expect one solution to solve all your problem.

  8. If you are using Microsoft CRM 4, make sure you have a later update rollup installed and some of the registry keys set to enable a more optimal usage of the Microsoft CRM Async service. See "Duplicate emails are sent unexpectedly from servers that contain the Async Service for Microsoft Dynamics CRM 4.0" http://support.microsoft.com/kb/2249156 Note: This was first released in Update Rollup 12 of Microsoft CRM 4. You can also optimize Microsoft CRM Async Service performance and processing if it is installed on a multi-core server by following the steps in this KB article - "How to improve Microsoft CRM Async Performance on multi-core servers" http://support.microsoft.com/kb/2489162. Note that KB 2489162 has been implemented in Microsoft CRM 2011 by default during the installation. The other thing to do to eliminate or reduce these timeouts is to use the SQL PSS Perf Wait Stats to collect SQL Traces and analyze them using a tool like SQLNexus - http:/sqlnexus.codeplex.com/ and tuning the top 5 to 10 most expensive queries using a tool like the SQL Server Database Tuning Advisor. You can see many other tips for optimizing performance for Microsoft CRM 4 in the following whitepaper: Optimizing and Maintaining Microsoft Dynamics CRM 4.0 - http://www.microsoft.com/downloads/en/details.aspx?FamilyID=ba826cee-eddf-4d6e-842d-27fd654ed893&displaylang=en
