Hi,

Today I stumbled into the following error message while was publishing SPD 2013 workflow:

Errors were found when compiling the workflow. The workflow files were saved but cannot be run.

Microsoft.Workflow.Client.WorkflowCommunicationException: The request was aborted: The request was canceled. Client ActivityId : 7a290e9c-0917-7088-afc4-e65fd25c5c0b. ---> System.Net.WebException: The request was aborted: The request was canceled. ---> System.ServiceModel.ServiceActivationException: The requested service, 'net.pipe://localhost/SecurityTokenServiceApplication/appsts.svc' could not be activated. See the server's diagnostic trace logs for more information.

Server stack trace:

Another symptom is that workflow cancels on start with the following error message:

RequestorId: f58f8045-c8ff-3ff0-d7d3-d4b4bb8bb7ba. Details: System.ApplicationException: HTTP 500
The requested service, 'http://ch02sp01:32843/60cb2361c56a44639e185aec7d585ba6/AppMng.svc' could not be activated. See the server's diagnostic trace logs for more information.

   at System.Activities.Runtime.ActivityExecutor.ExecuteActivityWorkItem.ExecuteBody(ActivityExecutor executor, BookmarkManager bookmarkManager, Location resultLocation)

The cause of the issues is very simple. There was not enough memory to start the service. So the solution is simple, just free up some memory.

Hope it saves somebody some time. If so, please, press upvote on the bottom of the post 🙂
