The workflow I have developed and deploy will not start start asynchronously when manually started in the SharePoint UI. Are there are any settings or tweaks I should be aware of that may prevent this?
Detail:
The workflow is created using Visual Studio 2005 and is deployed as a feature. A separate feature uses a feature receiver to associate the workflow to a list. AllowAsyncManualStart and AllowManual are both set to true on the SPWorkflowAssociation before it is added to the list.
The environment is WSS 3.0 w/MOSS running on a VPC. Performance is good (other than this issue). All the latest service packs have been installed including the latest SharePoint infrastructure updates. The SharePoint hotfix rollups have not been installed (I'm assuming these are rolled in to the Infrastructure Update).
The workflow contains a CodeActivity which copies items from one list to another. Depending on circumstances, the CodeActivity may copy around 5,000 items. If you start the workflow manually, the "Please wait while your workflow is started..." message will appear and remain until the workflow completes instead of returning immediately, allowing the workflow to run in the background.
Ideas or advice appreciated.
