Behavior of WorkflowServiceHost and AbandonAndSuspend on unhandled exceptions RRS feed

  • Question

  • We are using the WorkflowServiceHost combined with the SQL Server InstanceStore. We have configured the unhandled exception behavior to be "AbandonAndSuspend", which suspend any workflow instances going into error. We have noticed that sometimes suspended workflow instances are automatically resumed by the WorkflowServiceHost (without our intervention). We think it happens sometimes when we restart the IIS pool, but we currently can not reproduce this constantly.

    Is this a normal behavior of WorkflowServiceHost? Or is this not possible and either caused by a bug in our code or another bug/external cause?
