UBB.threads PHP Forum Software Community Forums UBB.threads 7 Version 7 Support Sporadic MySQL error

I am periodically receiving the following message on my forum:I'm receiving emails from my users asking what the problem is. It does not happen every time the forum is accessed, but it does happen frequently.

Each time I've received the message I've checked my MySQL server, but it always seems to be running fine.

It's telling you that it cannot connect to your mysql server; this is an issue you should take up with your host as their server isn't being reliable.
