Hi Guys, we just converted a 2,5 mln posts and 70.000 users BBpress 1.0 install to BBpress 2.2.1 (under WP 3.5). Conversion went ok, but now the server is busy with a continuously repeating query we cannot identify:

SELECT post_modified_gmt FROM wp_posts WHERE post_status = ‘publish’ AND post_type IN (‘post’, ‘page’, ‘attachment’, ‘forum’, ‘topic’, ‘reply’) ORDER BY post_modified_gmt DESC LIMIT 1  

Anyone an idea where this comes from?

I didn’t recogonize it of the top of my head but a quick search landed me here:

https://core.trac.wordpress.org/ticket/15499 & https://core.trac.wordpress.org/ticket/22742

So it looks like it is generated from RSS Feed requests and that would make sense.

Does your site use the same URL’s now RSS Feeds as it did before and what are your RSS subscribers numbers like?
