I wouldn't read to much into it at this point, guys.
At this point, we're waiting to hear back from the guys who run the Forums to find out if they have noticed anything out of the ordinary happening.
Once we hear something definitive, we'll pass along an update on it.
That looks more like the maximum number of database connections has been reached than SQLi

It went up to at least 6,012 visitors with only 8 to 10 members, but at that point I had to attend something else and didn't get back to check it again until about 9:12 am, only to find that the number was dropping back toward the normal visitor count. I'm not sure how high it reached before it started to drop again, but it didn't set another new record.
This event might be nothing to be concerned over, but I'm posting the above details just in case they might help someone to track down the source of all the additional traffic. Should it turn out to be search engine bots causing the additional traffic, it would be nice if their visits didn't count in the visitor totals so that a more accurate count of "real user" activity can be reflected in the Currently Active Users stats.
