I have created one long running workflow in asp.net 4.0.

enter image description here

This WF start once & never stop. I have start this workflow from my web application. In Global.asax,

protected void Application_Start(object sender, System.EventArgs e)
{
  var LicClient = new WFService.LicWFClient();
  LicClient.StartWorkFlow();
}

I have used some code activity for database transactions.

Process Replenishment - Check requests which are hold due to some reason then process to check it for full fill there requirements & if it valid then pass to next, other wise hold again. Send notification mail about it.

LicenseRequest - Check for valid request.

Sleep 30 Sec - Thread sleep for 30 sec.

Process on Request - Process on request & send notification mail about it.

Sleep 1 Min - Thread sleep for 1 min.

It works fine for me but on server getting me some issues.

  1. Work Flow stops after some time
    • this is not happen daily. So we start it manually.

  2. Error :

    The context is not currently tracking the entity. Parameter name: entity at System.Data.Services.Client.DataServiceContext.UpdateObject(Object entity) at LicenseWF.SaveLicenseData.Execute(CodeActivityContext context)

    • this happens with valid request but not all, getting one in 2 days.

If any idea, please suggest me. thanks in advance...
