Strange LAN access error

[Tolga Ceylan]

This is difficult to assess without specific details of your environment, but
assuming that your http headers are not really that large, 414 could be a sign
that you perhaps have a loop somewhere and forwarding requests between
your servers until you hit 414.

Again this is assuming that you have a 'proxy-set-header' in one of
these proxies,
which eventually overflows the http header. Perhaps your local LAN DNS is not
setup correctly, so your router and/or proxies form a traffic loop.
