This is rather odd.
There is no IP, no type of error, no error message, so it's a bit difficult to track it down.
Line 1622 is the query of the functions boardsModerated.
This is called probably from memberQuerySeeBoard that is used in a scheduled task: user_access_mentions.
The only thing that I could trigger an error there I think it's a wrong $id_member passed.
A 0 should not trigger an error (the query would return an empty result I think).
So a false/null? Or a string? But why? And why an error without anything else?
No idea. 
ETA: okay, I did some more tests.
Running the scheduled task manually I can see a query error and an undefined index in the scheduled task class, though... it's even more odd.
$user_see_board = memberQuerySeeBoard($row['id_member']);
log_error(implode(', ', array_keys($row)) . '<br />' . implode(', ', array_values($row)) . '<br />' . $row['id_member']);
This code, logs properly $row['id_member'], but the line just above generates an undefined index error 'id_member'
And it fails only when re-counting [SiNaN]'s mentions... LOL
