Increased rate of daily limit suspensions

From the start of July, there was an issue with the daily resource limit calculation. This resulted in much higher reported usage than was actually the case. The consequence of this was that many accounts were incorrectly suspended because of high daily limit usage. Especially CPU usage and IO usage rates increased substantially.

This issue was fixed on July 28, after which the rates dropped back to normal, so it appears the issue is resolved for now.
