I added a high traffic site to one of my VPS's and its killing that VPS and dramatically increasing server load average. http fails. MaxClients reached. Current setting (both locations) is 256. Tried adding to httpd.conf:
ServerLimit 500
NOriginally had no failed beancounters on this VPS (until after I increased the server limit and maxClients).
I will detail QoS setting below. First Hardware and OS Details...

#3 3 domains 1 with very heavy traffic (this is the one thats killing
