. You can get on the Beta program and try out this functionality. The beta for ArcGIS 10.1 is coming out very soon. Jay Sandhu That sounds promising.....silly question, how do I get on the Beta program?

OK....I'm back on this project. Still having problems with larger service areas and I'm desperate. I am able to solve for relatively small service areas (180-240 minutes) in just a few minutes. Solving for service areas up to 540 minutes. I've turned on Forced Chunking and set the edge chuck size down to 100,000. 200,000 did not work. It runs for 1-1 1/2 hours using only 5-12% CPU and then crashes. I also set the polygon trimming to 5000 meters (actually I've tried from 500 to 5000 and everything in between). Suggestions? Any chance there is a 64bit ArcMap coming any time soon that can use more RAM? Thanks, Jim

Actually I mis-spoke. The service area I'm calculating is 300 miles, not 300 minutes. I know this is an extremely large service area. But it did work without crashing when I broke the locations down to smaller datasets only processing 3 location the first time. I'm currently running the same 3 locations with the setting as you suggest and using the Solve tool rather than the toolbar. If this works, then I'll try it with 5 locations. Thanks 300 minute service area in some parts of the country may fail on 2 GB machines. Since you are running on a 64 bit environment with 6 GB, and if you are running ArcGIS 10.0, then it will be able to use up to 4 GB. It should work with the chunking on. I will suggest that you add a TRIM of 500 to 1000 meters otherwise the polygons will look like blobs. The trim should add couple of extra minutes to each solve but results in much better looking polygons. If it does not work then I will suggest that you run it as background GP process with Solve tool in the network analyst toolbox. Make sure to have created the service area layer AFTER you add the registry keys as that will make that service area layer use the registry settings. Jay Sandhu

I am getting the same error. I did the registry modification and am running the analysis now. Keeping fingers crossed (it takes a few hours to run...you'll see why when you see the size of the service area I am calculating). [INDENT]23 facilities Calculating 300 minutes away from facilties U-turns allowed Overlapping generalized polygons No trimming No line generation[/INDENT] Running on Win7x64, 3.33Ghz quad core Xeon, 6GB RAM While running analysis, machine never says that its using more than 4GB RAM so I'm not sure of memory is the problem....but I'm willing to try anything. I know this is a very large service area but it's what I need to run. Is it possible to run one this large? BTW-The service area is legal driving time for commercial trucks. We're trying to determine if service areas are large enough. Thanks, Jim
