Issue with Mosaic to New Raster tool

I am having a major issue with the Mosaic to New Raster tool when importing ASC files. It processes the first few files but not all of them. I thought it was a space issue and tried to split the input but this doesn�??t help.

For ex the output when I run the tool directly and in the python window is out1

So both processes are loading all the required asc files into the tool but they are not being merged and weirdly the result DEM�??s are in different zones of the band.



I tried to break the files up in to bands as I thought it was a space issue but actually I need each mosaic to be made of about 100 tiles. When I tried the process by splitting into bands, it just processed the first few tiles of each region as in the graphic below. The full script I need to run is attached. The csv_split.py just splits the csv into bands as I initially thought the issue might be lack of space but I have over 250GB of free space on my C: and terabytes on Z:\ (the scratch disc)











Best,
