I am duplicating the category tree with products works fine on my system while checking on live instance.
scenario
- Duplicate category and subcategory but not products works fine.
- Duplicate category with no subcategories but have products more then 1200 also works fine.
- Duplicate category and subcategory and their respective products not more then 500 works fine.
- Duplicate category and subcategory and their respective products more then 500 doesn't works fine and stuck on the controller giving 404 error instead of redirecting like other scenarios.MAIN ISSUE
