In Magento 1.8 when a customer place an order and if that order contains a product that has 1 item left in product inventory the customers receives friendly message saying "there was an order with your order" but the order get through and payment would be taken. If there is two Item with the same product this does not happen. also it becomes out of stock but the inventory stays 1.
So, the error I get with Payment transaction failed e-mail is:
SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '1499-0-1' for key 'PRIMARY'
1499 is product ID.
I enabled debug in mysql. and this is 'var/debug/pdo_mysql.log';

EDIT: error starts after this query in pdo_mysql.log:
## 2014-06-08 19:10:41
## 1716 ## QUERY
SQL: INSERT INTO `catalog_product_index_price_tmp` SELECT `catalog_product_index_price_final_tmp`.`entity_id`, `catalog_product_index_price_final_tmp`.`customer_group_id`, `catalog_product_index_price_final_tmp`.`website_id`, `catalog_product_index_price_final_tmp`.`tax_class_id`, `catalog_product_index_price_final_tmp`.`orig_price` AS `price`, `catalog_product_index_price_final_tmp`.`price` AS `final_price`, `catalog_product_index_price_final_tmp`.`min_price`, `catalog_product_index_price_final_tmp`.`max_price`, `catalog_product_index_price_final_tmp`.`tier_price`, `catalog_product_index_price_final_tmp`.`group_price` FROM `catalog_product_index_price_final_tmp`
We used to have a similar problem on magento 1.7, it happened because we introduced a "new" type of product that is a bundle of configurable products. In this case we had some products that were at the same time parent of some products and children of some other (the bundle ones) that way when _copyRelationIndexData was called by reindexProductIds catalog_product_index_price_tmp table was filled with some rows belonging to "composite products" causing the "Integrity constraint violation" when reindexEntity is called. Long story short we overrode _copyRelationIndexData method this way :
protected function _copyRelationIndexData($parentIds, $excludeIds = null)
{
if(!is_null($excludeIds) && is_array($excludeIds)){
$excludeIds = array_merge($excludeIds,$parentIds);
}
return parent::_copyRelationIndexData($parentIds, $excludeIds);
}
