I read a large dataset with a lot of pairs of origin and destination points and by moving the curson I calculate the different routes in arrow. However, after about 45 iterations the program stops and gives me an error message (Runtime error: Traceback (most recent call last):&nbsp; File "&lt;string&gt;", line 42, in &lt;module&gt; IOError: [Errno 9] Bad file descriptor). Note that I use the command arcpy.Delete_management so as to free some memory. I wonder if this has to do with overloaded memory and if so any suggestions?</SPAN><BR /><SPAN>Thanks</SPAN></BODY></HTML> Fri, 01 Jun 2012 11:04:20 GMT ChristinaMitsakou 2012-06-01T11:04:20Z &quot;Runtime error&quot; when it makes iterations https://community.esri.com/t5/python-questions/amp-quot-runtime-error-amp-quot-when-it-makes/m-p/384481#M30311 <HTML><HEAD></HEAD><BODY><SPAN>Hi </SPAN><BR /><SPAN>I use python in ArcGIS 10.1 in order to define the routes between couples of origin/destination points.
