ArcGIS Server 10.6 and ArcMap 10.6.1 for publishing.
I've built a cache of a small area using a mosaic dataset. When I view the cache rest endpoint i'm seeing missing tiles (or slivers) between 1:4000 - 1:6000 (1:5000 cache scale).
All tiles are 100% complete. All other caches being served from AGS are not displaying this issue.
Here's a picture:
All the tiles display as expected at finer/coarser scale ranges.
I've attempted to rebuild the 1:5000 scale a couple of times with no success.
Any ideas or comments would be greatly appreciated.
