Alex - it works ok for a few hours and then goes into overload again and again. As I write this, there are 11 cpvps above 5 (in the red). Mine is 3.18 but the overloaded ones cause phpBB on my site to time-out and not post messages properly because it can't update the MySQL database. phpBB is the only thing on my site and there are never more than two or three users posting at the same time.

This was not the case so frequently before the power blip.
