FME Desktop 2012
Symptom
FME 2012 may produce Application Errors running Python scripts that use external modules such as arcgisscripting.
Cause
Changes made in FME 2012 to improve Python usability in FME Server may cause FME to shut down its Python before large external modules have completely unloaded. This will raise an application error, even though the workspace completes.
Resolution
Setting the external object(s) to None at the end of your script will avoid the Application Error
Example:
# import ArcGIS scripting
import arcgisscripting
# Create the Geoprocessor object
gp = arcgisscripting.create()
# Do geoprocessing
.
.
.
# Unload ArcGIS object
gp = None
