ERROR 030024: Solve returned a failure.

When I solve for the nearest facility in python I get this error:

An error occured on line 122

ERROR 030024: Solve returned a failure.

Failed to execute (Solve)

The problem is I don’t have any info on why the solve failed. 

    arcpy.Solve_na(naNearFacil, "SKIP", "TERMINATE", "")
except Exception as e:
    # If an error occurred, print line number and error message
    import traceback, sys
    tb = sys.exc_info()[2]
    print "An error occured on line %i" % tb.tb_lineno
    print str(e)


I only get the error if I am running the script via idle and it works fine as a python tool in the MXD.  It also works fine in idle if the input facility list is smaller.  So I guess it could be a memory issue. 

Any ideas on what the problem is or at least how to get more info on why the solve failed.?

Python version I suspect

arcgis 10.0 - Network Analyst: arcpy's 'Solve' running out of memory - Geographic Information System...

and the link therein

GIS Geek: Set 32bit Executable LARGEADDRESSAWARE Flag to True

Check out PRO to see if the functionality is there should you wish to use a newer version of Python
