Database Error when sending emails out

[Mellymonster]

I am getting this DB error when sending an email out, does this mean that the table in the "Send Email to all users" is not in right? The email still sends though.

Database error in vBulletin 3.8.2:

Invalid SQL:

UPDATE session
SET lastactivity = 1244080955, location = '/forums/cadminp/email.php?do=dosendmail&do=dosendmail', inforum = 0, inthread = 0, incalendar = 0, badlocation = 0
WHERE sessionhash = '6da5cf8b72f53ceb1bc54f5743c52a1b';
