That does happen from time to time. What has bothered me for a week or so now, is that the site is getting very slow. It takes minutes instead of seconds to load sometimes, or it times out and I am not having that issue on any of my other normal sites, so I think it's here. Hope that gets resolved.
I got it last night and it says the configuration is set with too low a maximum # of connections to the database. Kind of one of those things where the first 100 people in it works fine for, its #101 that gets errors. As we grow, those #s have to get adjusted. It is a bit of a balancing act because the system reserves resources for the number of connections you specify. So set it too low and people cant get in, set it too high and its slow when you do get in.
I'm sure Mr. Admin will find a happy medium here shortly, just takes some time.
