I received a similar message:
WordPress database error: [Got error 127 from table handler]
SELECT SQL_CALC_FOUND_ROWS wp_posts.* FROM wp_posts WHERE 1=1 AND wp_posts.post_type = ‘post’ AND (wp_posts.post_status = ‘publish’ OR wp_posts.post_status = ‘private’) ORDER BY wp_posts.post_date DESC LIMIT 0, 21
Turning off my “Bad Behavior” plugin seems to have stopped this; could this be an attack against the anti-spam plugin against those using it?
