Weird timeouts, not sure if I've set the right threshholds

[mike]

On the proxy. I've changed the IPs and hostnames to protect the
innocent (except for the upstream IPs - which are the 10.13.5.x ones)

i'm not actually seeing anything for that request in the backend error
log. sometimes i see "client aborted connection" etc. but i enabled
the "fastcgi_ignore_client_abort on;" on the backend, and
"proxy_ignore_client_abort on;" on the proxy...
