Hello friends ... I am writing because I need your help ... Since a time ago from my hosting are warning me that the site is generating too many queries to the DB server to the point that pervades and the database server collapses ... that quieries are repeated every half second and that is unstoppable ... I leave you here a line of them so that you can tell me if you know what this is? He has given me to think that I have been the victim of some sql injection because this query does not make much sense ... I do not know ... I need opinions please ...

This is the query:

SELECT COUNT(*) FROM bbb_k2_items WHERE YEAR(created)=2014 AND MONTH(created)=7 AND DAY(created)=29 AND published=1 AND ( publish_up = '0000-00-00 00:00:00' OR publish_up <= '2014-07-31 17:55:09' ) AND ( publish_down = '0000-00-00 00:00:00' OR publish_down >= '2014-07-31 17:55:09' ) AND trash=0 AND access IN(1,1) AND EXISTS(SELECT * FROM bbb_k2_categories WHERE id= bbb_k2_items.catid AND published=1 AND trash=0 AND access IN(1,1) )

This query selects all the published posts written on 29/7/2014.
It does make sense but the time frequency does not.

Are you displaying posts by day in your site?

Are you using any caching for your site?

Well i don´t know, but i don´t have any module in my website that can be doing that queries...

Can be the CLOUD TAGS module do all those queries? Can you please take a look of my website?? www.5septiembre.cu
