i will try to setup a conditional access log - logging everything on
the site will be an immense amount of waste, here's all my buffers or
anything I thought might be relevant.

client_max_body_size 251m;   so i can accept 250 meg PHP uploads in POST
client_header_buffer_size 8k;
client_body_buffer_size 1024k;  an attempt to try to curb this buffering
large_client_header_buffers 16 8k;

other buffers (relevant or not):

fastcgi_buffer_size 8k;
fastcgi_buffers 16 8k;
fastcgi_busy_buffers_size 16k;

proxy_buffer_size 16k;
proxy_buffers 16 8k;

gzip_buffers 16 8k;

keepalive_timeout 30;
