Mark Boucher,
My team has been working with ArcHydro tools for a long while, and our team leader, a black belt in Python scripting, created a script that would do what GeoHMS did, so that our engineers wouldn't have to go through all of the Arc Pre-Processing steps individually. Lately we've been getting "MemoryError" issues, even on small basins. The only things that have changed in the script are minor tweaks to make the process faster.
On my computer, the process seems to get stuck at the Compute Basins, Reaches, and Nodes section, but the errors come at other places on other machines.
I've set extents, cleared the temp folder, and turned off background geoprocessing, but still am getting the error. Any ideas on where to go next?
You've been a great help on here, so I thought I'd ask the expert before calling Esri!
