Can you just confirm if this is a problem with my host. I've had a few of these now and i'm assuming in simple terms it means that its lost the connection to the database?

thanks

Your presumption is correct. Zenphoto attempted to do the query listed but did not get back a response from the database. SQL must have initially been connected, though, or Zenphoto could not have even started up, so maybe the query is causing SQL to crash.
