Proxy module connection timeout during file upload

[tommy]

Hi,

I use nginx in front of apache using the proxy module. I want to upload a 2 MB file which is then processed by apache+php. Processing takes about 3 minutes. After aprox 71 to 75 seconds nginx terminates the connection.

Error_log:
2009/09/08 19:27:07  6644#0: *1890 a client request body is buffered to a temporary file /usr/local/nginx-0.7.61/client_body_temp/0000000000, client: 10.228.115.254, server: _, request: "POST /Cooperations/ HTTP/1.1", host: "upload.mydomain.net", referrer: "http://upload.mydomain.net/Cooperations/CodeGeneratorCampaign/1/de/8"
2009/09/08 19:28:18  6644#0: *1890 upstream prematurely closed connection while reading response header from upstream, client: 10.228.115.254, server: _, request: "POST /Cooperations/ HTTP/1.1", upstream: "http://127.0.0.1:8060/Cooperations/", host: "upload.mydomain.net", referrer: "http://upload.mydomain.net/Cooperations/CodeGeneratorCampaign/1/de/8"

First message appears when fileupload is done. The second is the abort.

Here my nginx settings:

http {
    sendfile        on;
    tcp_nopush     on;
    keepalive_timeout 0;

    gzip on;
    gzip_min_length  1100;
    gzip_buffers     4 8k;
    gzip_types       text/plain text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript;
    server_names_hash_bucket_size 128;

    server_tokens off;

....
.....

server {
  .....
  location / {
        .....
        client_max_body_size       10m;
        client_body_buffer_size    128k;

        proxy_connect_timeout      190;
        proxy_send_timeout         190;
        proxy_read_timeout         190;

        proxy_buffer_size          4k;
        proxy_buffers              4 32k;
        proxy_busy_buffers_size    64k;
        proxy_temp_file_write_size 64k;
   }
 }
}

Thx + KR,
Tommy
