Automatically generated invaild URL In admin/config/search/redirect/404, I found a lot of invalid url, it's a lot of additional "products" on our url, for example, News/products/products/products/products/products/products;
LED-Replacement-Lamps/LED-RGB-Lights/products/products/products/products/products/products/products/products/products;

The "NEWS" is our Contents, but "LED-Replacement-Lamps/LED-RGB-Lights/" is 301 redirect I do by "URL redirects”. So I want to know it's the problem of "URL redirect" tool or others?

I have check the patterns,but i did not find the issue.
I want to know why there is many links with additional "product" repeat again and again?
Problem is in your  pathauto Patterns, go to admin/config/search/path/patterns1 and check your pattern, it seems you have a pattern that when each time  the content edited Url  added to your Url Alias again.

I guess something like this exists there

 products/[node:url]
