I'm getting a lot of this: "An unexpected database error occurred. Please try again later." (This is in the browser, while looking at my forum.) When this happens, my web server log is full of entries like this: I'm guessing the Google bots are going bananas (for whatever reason) and are eating up all my database connections. I tried increasing my MySQL max_connections setting slightly, but it didn't help. Is there a good way to prevent this problem?
