VB Database erros

[BlackJacket]

I keep getting these DB errors. Maybe around 5-10 a day -

Database error in vBulletin 3.8.1:

Invalid SQL:

			SELECT post_groan.postid AS postid
			FROM post_groan AS post_groan
			LEFT JOIN post AS post USING (postid)
			INNER JOIN thread AS thread ON(thread.threadid = post.threadid)
			WHERE post_groan.userid = 426
				AND thread.forumid IN(1,42,2,5,9,3,43,4,46,48,47,12,7,49,11,20,21,22,23,24,31,32,51,52,53)
			ORDER BY post.dateline DESC
			LIMIT 1000;
