image services go blank/checkerboard after 1:300 scale zoom

[LauraBecht]

Hi, so we had two image services spontaneously stop showing the images after zooming past 1:300.  They were fine earlier in the day and then boom.  My first thought after seeing the checkerboard was mosaic dataset and overviews.  So I checked them.  One had some path issues, the other nothing came back after an analyze.  I fixed the path issues, built overviews, no difference.  So mosaic datasets appear to be fine, and in pro I can add them and zoom in as far as i want.  But even when I publish a new service i get the same thing - blank screen or checkerboard after 1:300.  The third image service we have running is fine with no issues.

We are running on enterprise 10.9.1.  The datasets with issues are being run from file gdb's stored on the server local c drive with source data stored on a network drive.  The one without issues is run from a gdb stored on a network drive with source data stored on the same network drive. These services have run fine for up to 2 years now with no change, so not sure if location is the issue?

Has anyone seen this before?  I am kinda stumped.

@LauraBecht Maybe try checking which image is suppose to display when it goes blank for you. It sounds like this is not a cached image service, so it should have metadata associated with it when you click it.

If it's the overview that pops up as the broken image, maybe try checking in the file explorer for that image and see if you can view it on it's own in Pro. If it doens't draw, then try creating them again (sounds like you did that though).

If it's a source image tile that pops up as the broken image, do the same thing and find the tile in the file explorer and see if you can view it. It could be corrupt for various reasons.

Another option is copy the source data over to the server if you have room. I normally keep all my data on the image server, so everything that runs our image services is on one machine for the database to access.

I've had corrupt images display this behavior before, basically just coming up blank and I had to download a new image tile since the original was corrupt for some reason.

Have a good weekend

To update, we found the below post which led my IT team to determine the cause to be a permissions issue with the server.  The source images were fine as was the mosaic dataset.
