If you see this error in AppFabric dashboard you might be suprised, because the error is cause by some workflow activity, which is not a part of your workflow.

(1) 'Cancel' command failure:
The message could not be dispatched because the service at the endpoint address 'net.pipe://dado-nb1/TestServices/yourservicename.xamlx/System.ServiceModel.Activities_IWorkflowInstanceManagement' is unavailable for the protocol of the address.

This error is caused by stopped application pool. If you try to suspend or terminate the workflow instance and the pool is in the mean time stopped, the management endpoint (implicitly added by AppFabric) will not be able to communicate with your service.
