Thanks for your response Oleg. Here is what I discovered after returning to work. I left the browser up all night along with the tab that had the spinning activity icon. This morning the icon was not spinning. I refreshed the tab and it took me to the generator control panel. It shows that it has crawled and added 5 levels and over 53,000 pages. So, the generator was continuing to work throughout the night. And after refreshing the tab it began working again. So, far it is not giving me any timed out errors and it is continuing to add pages.
Also, of interest is that since it is working I went to the generator/data directory to delete the interrupt.log file and discovered it wasn't there. I had created an empty interrupt.log file and verified it was in that directory last night. I did this because I read in another post that when the crawler gets to that file it will stop. Why it is missing is odd.
Also, my web site is on a shared windows hosted server and the hosts tell me that if they change the pnp.ini file then it will change for everyone. They asked what I wanted it changed to and they will escalate the request. Is there a suggested setting for memory_limit and max_execution_time?
