Before a month I tried to generate a new XML sitemap for my site ([external links are visible to admins only]), i found that the configuration, I've setup before, all changed (like reset).
I tried to configure it again, and when I'm trying to run the crawler, its not completed....ended with fatal error (insufficient memory). (tried many different configurations, non worked).
Now I even could not started the crawling process.
Please help and advice.
