I am so confused - please validate this

I get this in my error log - normally I ignore it, except the swf
uploader being used seems to die and I am trying to narrow down why.
It appears to use a PHP script to inform the flash applet of the final
file size/etc. - very small, one line of text.

However, it keeps being stuck in the body request buffer - even when I
set

client_body_buffer_size 1024k;

Am I missing something here? I have something dump the contents of the
response out and it’s a single line of text. WAY under 1 megabyte.
Would probably even fit into 64k…

2009/10/25 15:31:36 [warn] 9179#0: *7808465 a client request body is
buffered to a temporary file /var/lib/nginx/body/0000003716, client:
18.18.31.200, server: foo.com, request: “POST /user/swfupload/put.php
HTTP/1.1”, host: “foo.com

That is the right variable, right? That’s what it seems to be, however
I am having issues still, even with the buffer size bumped up way
beyond normal.

Are there other variables I can tweak? Any other information anyone
could use?

The client_body_buffer_size is a directive, but not a variable.
A client body size is controlled by two directives: client_max_body_size
(a total max size) and client_body_buffer_size (up to this size nginx
will not store the body in temporary file). Could you log in access_log
“$http_content_length” to see the body length ?

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;

Only client_max_body_size and client_body_buffer_size are relevant here.
The first body part may be in client_header_buffer_size or in one of
the large_client_header_buffers.
