If these were the two associated callsigns on 26/07/2012...
RYR9VR aborted approach to LEMD at 20:12 at around 8000ft, right turn to 270°, then the one circle in the West at FL160, then climbed to FL240, landed behind LAN A340 at LEVC at 21:19UTC
No holding of 60 minutes anywhere.
RYR5389 aborted approach to LEMD at 20:14 at around 8000ft, right turn to the Southwest, then the one wide circle in the West at ca. FL120, then climbed to FL240, landed at LEVC 21:25UTC
No holding of 60 minutes anywhere.
The third one that may have been affected was RYR2054. Aborted approach to LEMD at 20:10 at around 5500ft, right turn to the Southwest°, then the one circle in the West at FL150, then climbed to FL280, landed at LEVC at 21:09UTC
Other traffic diverting LEMD to LEVC were LAN705, EZY1419, BEL3731, IBE36MY, AEA6138, IBS2491, however it does not look like a mess. Only, LAN705 overtook the preceeding RYR and EZY on approach, so most likely some reason to rush, too.
