I am suddenly having some issues publishing a service using ArcGIS for Server 10.3. About 3 to 4 months ago I was able to simply create a service and save a service definition and then publish that definition using ArcGIS Server Manager. Now it just "hangs" and never completes he publishing? Anyone have ideas on why its doing this.
I have also tried just publishing services directly through ArcMap 10.3 but that is not working either. I get the following error (see attachment). I also attached a screen capture of the GP results.
