ArcGIS Data Access Failure

[DaveTenney]

All,

   i have seen discussions here and there about this similar issue, but i wanted to ask it again...

we are seeing this following error in both 10.2.2 environments as well as our newer 10.5.1 environments:

ExecuteError: Data access failure, layer = Image, error string = Could not access data for layer or table Image during drawing§TilesWorker: Data access failure, layer = Image, error string = Could not access data for layer or table Image during drawing§TilesWorker: Data access failure, layer = Image, error string = Could not access data for layer or table Image during drawing

we see this when using our python scripts to update our map services. we have two maps: one with just vector data and one with vector and raster data. our scripts get through the vector only map just fine but when its time to update the map with the raster data we get the above error.

it seems like a fairly straight forward error...well kind of. it would appear to be a data access issue, but the odd thing is we haven't changed the data or where its located or the permissions of said location. so i'm a bit perplexed on this issue, and any help would be greatly appreciated.

thanks a bunch!

My biggest concern would be of bandwidth...

1) current setup where the vector and raster are together, you are only requesting the data once

2) separate services, now you are requesting the data twice(1 request for vector, 1 request for raster)

Im not sure if Esri has looking into this or not but that would be the main hesitation on my end.

after opening a ticket with esri support we seem to be making some head way...

i am very concerned about the behavior of ArcGIS Server, please see below:

i currently have the server set to a max of 2 instances of CachingTools. the two instances of .GPServerSync are crippling our machine! i have never seen this behavior before and the only thing that has changed on our machine is an upgrade from 10.2.2 to 10.5.1

Machine Specs:

Windows Server 2012 R2

16 GB Ram

Intel Xeon CPU E5-4620 v2

 thoughts?
