I'm getting the following exception (pasted below) when attempting to programmatically execute a workflow using SPWorkflowManager.StartWorkFlow(). The list item is coming from a CAML query, and the workflow is obtained after enumerating through a list's workflow associations (SPList.WorkflowAssociations):

wfmgr.StartWorkflow(item, workflow, workflow.AssociationData);

Any ideas?

Microsoft.SharePoint.SPException: Exception from HRESULT: 0x8102009B ---> System.Runtime.InteropServices.COMException (0x8102009B): Exception from HRESULT: 0x8102009B at Microsoft.SharePoint.Library.SPRequestInternalClass.AddWorkflowToListItem(String bstrUrl, String bstrListName, Int32 lItemID, Int32 lItemLevel, Int32 lItemVersion, Guid workflowPackageId, Guid& pWorkflowInstanceId, Guid workflowTaskListId, String bstrStatusFieldInternalName, Int32 lAuthorId) at Microsoft.SharePoint.Library.SPRequest.AddWorkflowToListItem(String bstrUrl, String bstrListName, Int32 lItemID, Int32 lItemLevel, Int32 lItemVersion, Guid workflowPackageId, Guid& pWorkflowInstanceId, Guid workflowTaskListId, StringbstrStatusFieldInternalName, Int32 lAuthorId) --- End of inner exception stack trace --- at Microsoft.SharePoint.Library.SPRequest.AddWorkflowToListItem(String bstrUrl, String bstrListName, Int32 lItemID, Int32 lItemLevel, Int32 lItemVersion, Guid workflowPackageId, Guid& pWorkflowInstanceId, Guid workflowTaskListId, StringbstrStatusFieldInternalName, Int32 lAuthorId) at Microsoft.SharePoint.Workflow.SPWorkflowManager.StartWorkflowElev(SPListItem item, SPFile file, SPWorkflowAssociation association, SPWorkflowEvent startEvent, Boolean bAutoStart, Boolean bCreateOnly) at Microsoft.SharePoint.Workflow.SPWorkflowManager.<>c__DisplayClass1.b__0() at Microsoft.SharePoint.SPSecurity.CodeToRunElevatedWrapper(Object state) at Microsoft.SharePoint.SPSecurity.<>c__DisplayClass4.b__2() at Microsoft.SharePoint.Utilities.SecurityContext.RunAsProcess(CodeToRunElevated secureCode) at Microsoft.SharePoint.SPSecurity.RunWithElevatedPrivileges(WaitCallback secureCode, Object param) at Microsoft.SharePoint.SPSecurity.RunWithElevatedPrivileges(CodeToRunElevated secureCode) at Microsoft.SharePoint.Workflow.SPWorkflowManager.StartWorkflow(SPListItem item, SPWorkflowAssociation association, SPWorkflowEvent startEvent, Boolean bAutoStart, Boolean bCreateOnly) at Microsoft.SharePoint.Workflow.SPWorkflowManager.StartWorkflow(SPListItem item, SPWorkflowAssociation association, String eventData, Boolean isAutoStart) at Microsoft.SharePoint.Workflow.SPWorkflowManager.StartWorkflow(SPListItem item, SPWorkflowAssociation association, String eventData)

It turns out that this exception is thrown if the list item already has a "terminated" workflow that is also flagged as "running".  e.g. an error occurred and you need to explicitly terminate the workflow for it to end.  I wrote up a summary here:
