    22> My only guess to the cause of this is that MYSQL is caching the results in the query cache even though the query contains `RAND()`. I've never heard of this happening though.

    4 That'd be strange indeed. Keywords such as NOW(), CURRENT_TIMESTAMP() and RAND() are all by-pass query cache. If I had to guess, I'd say that maybe the 2/10 servers have page cache enabled, or perhaps the results of `WP_Query` are being stored into persistent object cache. In any case, need more details.
