Manage tile cache partially fail with no error message

Question

Hello all

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 xyz.done file does not exists for each xyz.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.

Any ideas?

Thanks

Hi Mody,

We have the same issue.

As for now, two reasons found:

1) Mosaic dataset has overviews with a broken path to the file.

Solution:

- Run Export Mosaic Dataset Path tool with Export Mode: Broken.

- Delete the overviews.

- Rerun Manage Tile Cache tool

2) Manage Tile Cache tool runs with Area of Interest

It is a known bug fixed in version 10.5.1.

Mody,

I had just the server placed in the data center and no image server.

The caching happens on the server the server so I'd assume the number of cores should be more on the parent server compared to the client server.

Hi Shantonu

We have a virtual machine with 40 cores that call an image server on another machine with 12 cores.

Did you just run the local machine with 90% and not 50% or are you talking about the image service machine?

Is it possible that the number of cores on the client should not be bigger than the number of instances for the image server machine?
