Your index.php seems to require the value of HTTP_HOST to be set, which
requires an HTTP/1.1 connection being made by whichever client is making

The timing of this chatter, however, is less than frequent (ie. it isn't
every polling cycle) which perhaps points to a load-related problem. The
fact that the Apache errors you posted do not correlate to the nanny
logs says to me that you either have a clock drift problem (common with
virtual servers) or some other problem we can't see.
