DB errors when posting large posts
 

Any ideas, as I get this from time to time when under a average load and trying to post a large thread. Thanks for any ideas....

Database error in vBulletin 3.8.6:

Invalid SQL:

SELECT thread.threadid, MATCH(thread.title) AGAINST ('edited') AS score
FROM thread AS thread

WHERE MATCH(thread.title) AGAINST ('edited')
AND thread.open 10


LIMIT 5;
