What network dataset are you using and how far apart are the incidents/facilities.</SPAN><BR /><SPAN>Perhaps you can make sure that hierarchy is ON or if the hierarchy is not ON, then make sure a distance cutoff is in place so that in case there is no path between some incident/facility combination it is not searching an entire nation wide network with an exact solve and running out of memory.</SPAN><BR /><SPAN>Regards,</SPAN><BR /><SPAN>Jay Sandhu</SPAN></BODY></HTML> Mon, 15 Aug 2011 15:46:08 GMT https://community.esri.com/t5/arcgis-network-analyst-questions/out-of-memory-while-generating-closest-facilities/m-p/179155#M1875 JaySandhu 2011-08-15T15:46:08Z Re: Out of Memory while Generating Closest Facilities https://community.esri.com/t5/arcgis-network-analyst-questions/out-of-memory-while-generating-closest-facilities/m-p/179156#M1876 <HTML><HEAD></HEAD><BODY><SPAN>Yeh....2TB hard disk space and 12GB memory.
