With database loging on, non registerred users can't open threads, they can see the listing, but can't open threads as they are getting a database error:

Database error:
The database has encountered a problem.

I also get such DB error emails:

Database error in vBulletin 3.8.6:

Invalid SQL:

							INSERT INTO lgv SET 
							ipaddress =  '79.142.126.22',
							firstaccess  = 1291283798,
							views = views + 1,
							lastactivity = 1291283798;
