Find this query

Hello all,

i need to find where this query is being made.

SELECT p.* FROM wp_posts AS p  WHERE p.post_date < '2011-12-19 08:41:31' AND p.post_type = 'post' AND p.post_status = 'publish'  ORDER BY p.post_date DESC LIMIT 1;

Already seen on previous / next and comment it but it still executes…

anyone has an idea ?
