This is a new problem that emerged; I'm trying to publish a map image service to our Portal in Enterprise 10.8, with data as a reference to our registered enterprise geodatabase. There are no warning messages pre-publish, but it fails everything with a link to view the logs. On our server manager and Server Admin logs is see various errors related to the PublishTools.GPServer. No error reports related to this are in our server logs directly on the server machine.
The Data Store is registered, and I even tried added a Portal item of the registered database in Server Manager to accommodate the 10.8 changes.
