These are my first runs of the generator. Initially it did not appear to be getting very far and so I excluded a particular type of link. The excluded link was to about 650,000 generated pages. This would leave a remaining estimated 400,000 links.
After the generator had been running for an hour+, I looked to see how far it had gone by pressing "view sitemap" button and then the "crawling" button. I have repeated this a number of times. Each time it reports that it has crawled 1040 and added 1032 in sitemap and the same current page:
Updated on 2018-02-23 06:58:00 (232 seconds ago) , Time elapsed: 0:00:29,
Pages crawled: 1040 (1032 added in sitemap), Queued: 413, Depth level: 2
Current page: public/cemetery.php?cemetery=2394 (0.0)
I resume by clicking the "Continue the interrupted session" box and pressing the "run" button.
The website being crawled is on its own 950 dedicated server.
