I have an image service I've successfully cached previously. It had four empty scales 1:50, 1:100, 1:250, and 1:500 I created in order that the Geocortex viewer would permit zooming closer than the cached levels.
I have found need to populate the cache at 1:500, and was able to get perhaps a third of the service extent to do so. The table below shows the Cache Status where it is stuck, despite that Level 17 is currently underway for the dozenth or so attempt.

The trouble is the tile count never changes, despite my running Manage Map Server Cache Tiles with each attempt using an Update Extent shapefile covering a progressively smaller fraction of the area needed. So after three hours on an extent of just 30 sq. miles, the job details URL reports 0% completion on each line, with a different Estimated Time Remaining that grows larger and larger before dropping back to begin growing larger again.
The Logs in AGS Manager report what I suspect may be the reason for no tile creation:
SEVERE | Aug 15, 2016, 1:21:23 PM | Error exporting image Wait time of the request to the service 'public/swoop2015_mosaic.ImageServer' has expired. | Rest |

I don't know what to try next. I have already restarted the image service with no change in behaviour.
Short of contacting Esri tech support, what should I try to correct this issue?
Thanks,
Justin
