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
