Every time i did the following operation in Joomsef:
- generate xml sitemap
- ping google, yahoo or Bing
- process indexed link in sitemap
Joomla System return in the default admin page

Every time i did to crawl the website,
after about 2 minutes it stops with errors. If i continue, same error again and again.

I saw this issue since few days ago, when i update joomla and other components.

Hi,

The problem with sitemap is usually caused by too many URLs being displayed on one page thus exceeding the POST variables count limit. Try changing number of displayed URLs for example to 20.

For the website crawler, please try checking your server's errors log to see if there is any PHP error encountered when the website crawler stops with an error.
