I've started receiving the error below when I try to add new products to my site. I can no longer add any new products as I get an error telling me to refresh the page and try again. When I checked the logs on my site I get a PHP Fatal Error as below. Is there something I can do to fix this? I guess this is related to my products table in mysql?

Code:
PHP Fatal error:  1062: Duplicate entry '2147483647' for key 1 :: insert into zen_products (products_quantity, products_type, products_model, products_price, products_date_available, products_weight, products_status, products_virtual, products_tax_class_id, manufacturers_id, products_quantity_order_min, products_quantity_order_units, products_priced_by_attribute, product_is_free, product_is_call, products_quantity_mixed, product_is_always_free_shipping, products_qty_box_status, products_quantity_order_max, products_sort_order, products_discount_type, products_discount_type_from, products_price_sorter, products_image, products_date_added, master_categories_id) values ('0', '1', 'test', '0', null, '0', '1', '0', '1', '0', '1', '1', '0', '0', '0', '1', '0', '1', '0', '0', '0', '0', '0', '', now(), '36') in /home/mystore/public_html/store/includes/classes/db/mysql/query_factory.php on line 120
