I was running the raster to TIN tool on a 32 bit float mosaic dataset DEM and it ran for a week on my virtual machine using ArcCatalog 10.3.1 and when it finally said complete it had only processed half of the DEM? I have attached an image, has anyone ever seen an output like this? There were no errors listed in the results window but it did take 155 hours to run on this massive dataset. I ran Create TIN and Raster to TIN before on the same dataset and both failed with memory errors but this time it seemed slow but working. The red lines appear to be gaps in data but my mosaic dataset is perfect. Any advice you all may have would be appreciated.
