Stopping wordpress cacheing _rss in the wp_options table

[the-sexy-slug]

Hello

 

Is there a way to stop wordpress from cacheing _rss in the wp_options table because my database size when I started was under 1 meg and a few days later it was 19 megs and fill of _rss entries. This is proberbly due to a plugin that I do not want to disable. I would rather block the _rss enteries from being cached in the wp_options table of the MySql Database.

 

I know about clean options plugin and options manager plugin. I would rather stop the cacheing automatically if possible.

 

Thanks all in advance
