Timeout during heavy loaded tasks on MS Dynamics CRM 4.0

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.

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.
