Not sure if helpful but about 5 months ago my site started having that exact error. The logs showed that 90% of the traffic was coming from a single ip address. I had that ip address blocked and the server load dropped back to normal. Not saying that is going to be the solution here but if a large percentage of traffic is coming from one ip address, block that one does work. I should note that the ip address was blocked in the hosting control panel not phpBB.
