Hello, the newly installed Unlimited sitemap generator seems to be trawling pages as I see 'crawling already in progress', however most of the 'progress' window is taken up by a standard '404' page from my site, unless i go to other tabs and back again a few times. i also have a few lines (6 at present) saying "Fri Jan 27 2012 19:01:18 GMT+0000 (GMT Standard Time): resuming generator (120 seconds with no response)" below. Something isn't right. It's a large site with nearly 30,000 pages. I have a 5 second delay after 5 set as I had problems with cpu load.
