I have been testing the same workflow on several different locations of the same DEM. The current extent of the DEM that I am attempting to process is Top: 1823546.09235, Left: 1136672.44933, Right: 1156673.44933, Bottom: 1798546.09235. The DEM is one foot by one foot horizontal resolution, ESRI GRID, 32-bit floating point projected in Illinois State Plane East (WKID 6455) coordinate system. Here are links to the data source on AGOL and the REST service:

The workflow is pretty closely based upon the "Basic Combined Terrain Processing" model in the Terrain Preprocessing Workflow toolbox. I have only successfully run the workflow once or twice, otherwise, I get the same error message at the same step in the workflow when the Drainage Connectivity Characterization tool is run. This is the error message from the current area I am attempting to process:
Generating final drainage link between pitted drainage areas for 4222 drainage boundary lines. (dt= 539s)
System.Runtime.InteropServices.COMException (0x80041055): The cursor has been invalidated because the edit operation has stopped.

Failed to execute (DrainageConnectivityCharacterization).

Is there anything in this error message that may indicate what the problem is?
