I have multiple workflows that use an Invoke Workflow task to call other workflows that build our student and employee folders within our repository.  We have used this for a long time but it has come to my attention that several instances across several different workflows have a "Waiting" status and the common denominator seems to be on the Invoke workflow for either the create employee record or the create student record tasks.  We recently updated to Workflow 10.4 in April.  In each case only two variables are being passed, the associated ID (pulled from a previous query task)  and the initial workflow name which is a static variable on each workflow.  We did do a complete stack restart this morning and instances started today have completed successfully.  We have done the routine troubleshooting techniques of restarting workflow and subscriber and updating the task within a workflow to not wait for the invoked workflow to finish running, even disabled the task and published the change to all running instances.  Anyone have any idea how to get the task Jared loose so the rest of the workflow can process?
