I've searched the board, and tried just about every combination of settings.  However, my generator keeps stopping.  After several minutes, all I see is this:  "Already in progress. Current process state is displayed:" followed by some stats that do not update.  I waited hours, and my sitemap just doesn't finish.
Can someone please provide details on the optimal settings that should be used?  I am hoping to get this setup so it runs on cron eventually.  Can someone help with this?  Please?
