A workflow that unloads when a delay activity is triggered does not resume automatically even after the scheduled time has lapsed in Microsoft Windows SharePoint Services 3.0. The status of the workflow that is displayed on the SharePoint Services workflow status page remains “In Progress."
This issue may occur because of the following causes:
Cause 1The hotfix that is described in Microsoft Knowledge Base article 932394 is not installed on the computer.
Cause 2A workflow sometimes unloads before a timer event is scheduled to resume the workflow. If a timer event is not scheduled, the workflow will never resume.
Cause 3An issue occurs with the SharePoint Timer service. You can verify the issue by testing other Timer service functionality. For example, test incoming e-mail to create a list item.
Cause 4The SharePoint timer is not configured to run at the correct time. Delay activity in workflows is processed by the SharePoint Timer service, and workflows resume according to the schedule of the workflow timer job. By default, the timer job is configured to run every 5 minutes. For example, workflows that are configured to resume in 5 minutes may resume after 9 minutes and 59 seconds.
Cause 5The workflow assembly in the Global Assembly Cache (GAC) is overwritten. This issue occurs when you update the workflow assembly, and you overwrite an existing workflow assembly. In this case, the Timer process uses the old version of the workflow definition. The workflow does not resume because the old version of the workflow assembly is overwritten, and it no longer exists.
Typically, workflow in the GAC is overwritten in the following circumstances:
Cause 6The status of the workflow that is displayed in SharePoint Services remains “In Progress” even though the workflow does not resume.
Resolution for Cause 1To resolve this issue, follow these steps:
Resolution for Cause 2Install the Windows SharePoint Services 3.0 update that is described in the following Microsoft Knowledge Base article:
(http://support.microsoft.com/kb/953749/ )Issues that are fixed in Windows SharePoint Services 3.0 by the Windows SharePoint Services 3.0 Infrastructure Update
The Windows SharePoint Services 3.0 Infrastructure Update resolves this issue by scheduling a timer event.
Resolution for Cause 3You can use the following methods to troubleshoot issues that are related to the Timer service:
Resolution for Cause 4To work around this issue, run the following command to set the correct interval for the workflow timer job, and then restart the SharePoint Timer service:
Stsadm –o setproperty –pn job-workflow –pv interval for running the workflow timer job
Resolution for Cause 5Restart the SharePoint Timer service.
Note This resolution applies to only newly created workflow instances. It cannot correct the existing workflow instances that are already affected. You can use a version number for each assembly that is created to track the new and old workflow instances.
Resolution for Cause 6Verify the Unified Logging Service (ULS) log files for error messages, and then resolve the issue accordingly. Typically, this issue occurs if the workflow does not handle an exception and crashes.
Resolution for Cause 7Verify loop construct issues in workflow definitions. Make sure that the InitialChildData property on Replicator activities is bound to a data object.
