Mosaic dataset failed - Connection to local worker service lost?

[xaviermurray]

Hi all,

got this error message when trying to mosaic a bunch of DSM raster datasets...

interestingly, I literally just successfully created a Mosaic Dataset of the DEM collection form the same area, in the same format.

can anybody enlighten me on what this means so i can troubleshoot?

cheers,

Hi Xavier, 

May I know what is the version of ArcGIS Pro are you using?  

It is possible one of the rasters (DEMs) pixel properties are not the same as mosaic dataset you have created, please try to add few at a time to isolate the issue 

Hope this help!

Thanks Hamed,

Version 2.6

ill have a go at tracking down the culprit.

interestingly enough it seemed to load all of the raster in, but fell over when trying to generate overviews / histogram / stats etc...

What does that connection to local worker service message mean by the way?

is that just a generic fault code for the script / tool failing?

cheers,

Hi Xavier, 

Local worker service is part of windows which ArcGIS Pro uses to utilise multiprocessing, might be something went wrong with windows. Please make sure you have installed ArcGIS pro patches. 

Failing to creat overviews might be something to do with files and permissions. Can you open mosaic dataset after loading DEM's and view it on ArcGIS pro?

Thanks Hamed,

so based on that info above, I changed the parallel processing factor to blank instead of 70 and the process worked...

to answer your question though I could end up opening the DEM mosaic dataset in pro - i just had to manually build the overviews and statistics/histogram. 

looks to be all good now, thanks for your help
