 Hello,

 as I explained in the forum, I have detected an strange error with
 taxonomies. They get a random 404 error when receiving lot of traffic. I
 have reinstalled a clean WP, removed all plugins, and assigned the WP
 default theme, but still getting the 404. I have done several tests and my
 conclusion is that it only happens with custom structure permalinks. For
 some reason, WP randomly doesn't understand the taxonomy URL and ir server
 a 404. This is what I get when it works well:

 request] => blog/news/the-green-car
 [matched_rule] => blog/news/([^/]+)(/[0-9]+)?/?$
 [matched_query] => fotos=the-green-car&page=
 [did_permalink] => 1

 The same taxonomy page shows this when 404:

 [request] =>
 [matched_rule] =>
 [matched_query] =>
 [did_permalink] =>

 Here some details:

 - It never happens without traffic.
 - It never happens with default permalinks.
 - It never happens with post types, categories, pages or tags, only with
 taxonomies.
 - It also happens with the default TwentyEleven Theme and with any plugin
 installed.

 I'm very fustrated with this as every day I'm getting thousands of errors.
 Any suggestion will be apreciated.

 Thank you.
