This page contains the following errors:
Below is a rendering of the page up to the first error.
Here my link to my sitemap : ... sitemap/sitemap.xml
Did any boddy have any idea what I should do to make it correct?
It looks like yoursitemap stopped rendering just before it got to the products, your site might be suffering from an old bug in Magento, that causes the system to creat many many redirects. You can check for this by going in the admin:
Catalog > URL Rewrite Management
If there is an absurt amount of URL's here, that is your problem.
Depending on the age of your site, and how much seo value is in it, you can either try and sort this out manually, or just truncate the table core_url_rewrite, and then running the URL indexer in the admin again.
