I have produced rather a large model in Arc10, service pack 4. I have a few Near Tool processes within the model. When I run the model as a whole it will hang on a couple of these Near Processes and just won't carry on, or takes ages and write the information as -1 only!
If I have the model open in edit mode and cancel the process when it starts to hang, I can carry on where it stopped and the near analysis works fine, so there is nothing wrong with any of the inputs etc.
I just need to be able to run the whole Model in one go without this hanging problem, anyone have any ideas?
