I think this is a thread you need to take a close look at, It seems that certain kernels are causing overly high loads when vbulletin forums are used.

Also take a look at the links on that page, especially those to centos.org, it seems that certain kernels cause overly high resource usage on certain configurations of apache.
I believe it's in the best interests of both the company as well as the customer that this issue be addressed, because Vb is such a popular and well used forums script.
For the record, I've been experiencing somewhat erratic high loads on my vps occasionaly, sometimes loads spike 10 fold, even though there is no perceptable change in website traffic/activity.
thanks
