I still got a CTD, but at least got an error message this time around. So just to test, I switched back to Autopurge plugin and undid the changes to the INI files. I don't know if the issue came as the result of that, or on its own, but I'm on my way to Primm, and when I get close to it I get a CTD without any error messages. Recently followed all the steps in the Performance Guide.
