After update to 1.7 my site hangs up. After some investigation I found that oxwall is running some SQL query, I believe for converting Mailbox plugin on the first run. The problem is that it runs endlessly and hangup the site (took several hours w/o success). I've ran this in phpmyadmin and found that this is very unoptimized query for my 260 000 messages in table. Therefore 1.7 simply hangs on very first page request. Any ideas how to upgrade Messages module?
The SQL query from mysql processes list:
SELECT *FROM `ow_mailbox_message` AS t1JOIN (SELECT MAX( TIMESTAMP ) AS TIMEFROM `ow_mailbox_message`GROUP BY `conversationId`) AS t2 ON ( t1.timeStamp = t2.time )LIMIT 1
