I'm teaching a GIS course this semester that I've taught for many years using similar if not identical workflows. A reoccurring problem has been popping up this fall whereby a geoprocess fails to generate results while suggesting that it ran successfully.
Here are the symptoms:
- Once the geoprocess is executed, the green check mark pops up indicating that the geoprocess tool ran successfully. The green check mark usually pops up shortly after executing the geoprocess (suggesting that the process may not have really run);
- No output file is generated;
- The geoprocess shows up in the Results window pane with the "hammer" icon but the message tab is empty;
- Rerunning the same geoprocess results in the same outcome;
- If the MXD document is saved, closed then reopened, the geoprocess shows up under the Not Run tab of the Results window pane.
Here's the workaround:
- Saving, closing then reopening the MXD and re-running the same geoprocess from the Results window pane generates the desired output.
A few additional notes:
- We're running ArcMap 10.6.0.8321 on Windows 10. This problem manifests itself on Dell AIO 5720s and Dell Optiplex AIO 5250 hardware.
- This has happened on several occasions throughout this semester using different geoprocessing tools. Some tools that come to mind are the dissolve tool, point density tool and raster calculator.
- At times, this has happened to several students running the same geoprocess during a lab exercise (suggesting a quasi-random trigger). In such a scenario, the students (24 in the class) run the exact same series of geoprocesses then encounter the problem on a subsequent geoprocess. On one occasion, about a third of the students encountered this problem whereas the other students did not.
I haven't had luck finding a description to this problem on the web so I'm not sure how unique this is. Anyone else experience this anomaly?
