We run the Manage tile cache tool often to create caches.
The data source is image service and the target cache can be 1-5Gb in size. The process can take up to 2-4 hours.
The process ends successfully.
When we check the cache we found that is some levels in some area we see white screen.
Checking the disk sizes some levels sizes are smaller than expected.
Checking the directories on-disk I found that for the levels with problems the XX.done file does not exists for each XX.bandle file.
Yet the tool itself and the server of the source image server does not show any errors.
Trying to use the manage tile cache again with the "recreate empty tiles" help some time but not always.
