[shahzaib shahzaib]

Hello,

       We recentyl changed our ip of the server to upgrade port to 2Gbps
but after upgrading port, we are unable to upload .flv video upto 4mb.
Everything was working fine before the up-gradation. Following is the
nginx.conf file. Please i need a quick help :-

 user  nginx;
worker_processes  16;
worker_rlimit_nofile 300000; #2 filehandlers for each connection
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  6000;
    use epoll;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    client_body_buffer_size 128K;
    sendfile_max_chunk 128k;
    client_max_body_size 800m;
    client_header_buffer_size 256k;
    large_client_header_buffers 4 256k;
    output_buffers 1 512k;
#   fastcgi_buffers 512 8k;
#   proxy_buffers   512 8k;
#   fastcgi_read_timeout 300s;
    server_tokens off; #Conceals nginx version
    #access_log  logs/access.log  main;
    access_log off;
    sendfile        off;
    #tcp_nopush     on;
#    gzip on;
#    gzip_vary on;
#    gzip_disable "MSIE [1-6]\.";
#    gzip_proxied any;
#    gzip_http_version 1.1;
#   gzip_min_length  1000;
#    gzip_comp_level  6;
#    gzip_buffers  16 8k;
# You can remove image/png image/x-icon image/gif image/jpeg if you have
slow CPU
# gzip_types    text/plain text/xml text/css application/x-javascript
application/xml application/xml+rss text/javascript application/atom+xml;
    ignore_invalid_headers on;
    client_header_timeout  3m;
    client_body_timeout 3m;
    send_timeout     3m;
    keepalive_timeout  0;
reset_timedout_connection on;

Best Regards.
