I'm working with Visual Studio 2010 and have a workflow where I'm trying to resume a bookmark. The bookmark appears to be getting set just fine, but when I try to run the code below to resume it, I get an entry in the InstancesTable in the persistence database with the SurrogateLockOwnerID field set to an integer, usually this field is null, and I can no longer do anything with the workflow. I think this is indicating that I have some kind of blocking lock going on, but I can't find any references anywhere to the SurrogateLockOwnerID. Does anyone know what is causing this, and how to fix it?

            WorkflowApplication workflowApp = new WorkflowApplication(new WebCARSWorkflow());
            workflowApp.Extensions.Add(new SqlTrackingParticipant(ConnString));

            InstanceStore instanceStore = new SqlWorkflowInstanceStore(ConnString);

            workflowApp.InstanceStore = instanceStore;

            workflowApp.Load(WorkflowInstanceId);

            workflowApp.PersistableIdle = (waie) => PersistableIdleAction.Unload;

            Approver actualApprover = new Approver(ProcessingStatus.Awaiting, my_RDA_Role,
                "RDAGetPlayersFromExternalRoleURI", 14);
            actualApprover.ActionDate = DateTime.Now;

            Player actualPlayer = (Player)GetPlayer(login);
            actualApprover.ActualPlayer = actualPlayer;
            actualApprover.ApproverAction = action;

            workflowApp.ResumeBookmark("ErrorOccurredBookmark", actualApprover);
