"ERROR: request not found in the TrackedRequests" message logged each time a workflow starts

SYMPTOMS
Consider the following scenario:

You have a standard Team Site and you create a new workflow using SharePoint Designer 2007 using a site owner account EXCEPT SharePoint System (see http://support.microsoft.com/kb/953289)

The workflow is set to start "On Item Creation"
Only action configured for the workflow is Pause for duration - set duration 0 min.

You open the site in Internet Explorer as Contributor and create a list item to trigger the start of the workflow .

Result:
The workflow starts and logs a "request not found" error. The workflow runs to completion.

The error in ULS resembles :

ERROR: request not found in the TrackedRequests. We might be creating and closing webs on different threads. ThreadId = 15, Free call stack = at Microsoft.SharePoint.SPRequestManager.Release(SPRequest request) at Microsoft.SharePoint.SPSite.Close() at Microsoft.SharePoint.SPSite.Dispose() at Microsoft.SharePoint.Workflow.SPWorkflowAutostartEventReceiver.AutoStartWorkflow(SPItemEventProperties properties, Boolean bCreate, Boolean bChange, AssocType atyp) at Microsoft.SharePoint.Workflow.SPWorkflowAutostartEventReceiver.AutoStartWorkflow(SPItemEventProperties properties, Boolean bCreate, Boolean bChange) at Microsoft.SharePoint.Workflow.SPWorkflowAutostartEventReceiver.ItemAdded(SPItemEventProperties properties) at Microsoft.SharePoint.SPEventManager.RunItemEventRe…




CAUSE
In this scenario, the behavior is by design. In general this is an indication of a risky coding pattern, which is why there’s a warning, but in this case it is less clearly an indicator of a specific issue. The risk is only partially that of a memory leak, in that passing objects around between threads unexpectedly reduces the ability of our framework code to ensure that resources like SPRequest objects aren’t leaked (particularly in error situations).


RESOLUTION
If the occurrence cannot be associated to a memory condition, the message can be safely ignored. Use the performance monitor to assert whether or not the memory condition exist.
