yeah, i issued the request manually, there is no PHP there.
that could have been a client timeout or something for all i know. i am sure with a few million requests per day there will be a handful of crappy connections, proxies, tor exit nodes changing, etc...

The first line is error in the middle of ics2.flv transfer. The last two are did not get responses at all: "while reading response header". I think these two are handled by PHP and it may be slow. But the first timeout of static FLV is strange. Are you show that it handled by nginx but not PHP ?
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...

The timeout errors has no relation to buffers. These errors usually means that backends are too slow.
What should I look at then to speed them up?
The backends are Linux, NFS server is FBSD7, proxy server is Linux. Any pointers are appreciated.
Could you show some timeout messages ?
