Keep getting this SQL DB error emailed to me

[mikeee]

Just upgraded to 4.1.7 and I am getting this error email about 40 times a day and I cant find the error, I visit the referring URL and it works fine. No complaints from the board members either.

Any ideas?

Database error in vBulletin 4.1.7:

Invalid SQL:

	SELECT infractionid, infraction.userid, points, username
	FROM CSR_infraction AS infraction
	LEFT JOIN CSR_user AS user USING (userid)
	WHERE expires <= 1318461771
		AND expires <> 0
		AND action = 0;
