First I noticed the following in my web server error logs, very constant;
Apr 14 09:42:59 cweb93 httpd[6567]: [error] [client 192.168.1.76] PHP Notice:
Undefined index: HTTP_HOST in /var/www/html/i

Looking on master lvs, I see;

All of the servers on ESX guests and while the lvs logs are relatively quiet
other than the above, the web logs are filling with constant non stop chatter
from the lvs servers. I've looked everywhere I can to figure this out, have
found a few leads such as memory settings in php.ini but not much else. Perhaps
someone on this list can help shed some light.
Thanks very much.
