I was looking through gidgets for bid and on page two there was a strange box at the bottom.

That error means that so many different pages (people) were trying to access the database that it hit the number-of-connections-at-the-same-time limit. It's not a coding bug. I will, however, look into what I might do about it.
Thank you Silv, I didn't think it was a coding bug since it only happened that once, but it surprised me.
