Sitemap has run on cron succesfully for about 4 months. Last week it stopped and shows this message in the crawl section:
Continue the interrupted session (2008-07-27 04:46:01, URLs added: 3585, estimated URLs left: 14396)
The site has 3585 pages so was complete - don't know what the estimated 14396 are?
Anyway, if i restart the sitemap it appears to run but then fails. The above error message remains. Any ideas how to fix it please?
