Hi,
Local ESRI support cannot reproduce this issue - please help!
ArcGIS Desktop and Server 10.3.1
Steps to reproduce are ALL in the following list
1· I stopped some running image service (service1)
2· I opened Service Properties
3· I pressed Caching---Advanced Settings - crashed
Currently (after 1,2,3), I cannot publish a new image service
4 I try to publish a mosaic dataset as Image Service (different name from service1)
5· I have Service Properties opened
6· I press Caching – crashed (the same error window)
