File Upload fails for large files

Hi,
I am using mongrel with nginx and I am facing problem when I try to
upload a large file. After googling about this, I came to know that I
need to configure nginx.conf file by setting 'client_max_body_size'
to
a value of desired maximum file size. I did that but still it does
not
seem to work. Files above 200 KB do not get uploaded. I also get a
weird error about sockets (Given below the nginx.conf file)
What am I doing wrong? Please help.

My nginx.conf lokos like this:

user postgres ;
worker_processes 2;
error_log /var/www/webapps/FileSharing/log/error.log notice;
pid /var/www/webapps/FileSharing/log/nginx.pid;

    worker_connections 1024;

Its fixed.

We were using a Javascript to submit the form that held the file
field. When we used a submit button instead of the javascript, it all
started working properly. I wonder whats wrong internally but for now,
the code is working :-). If you are doing something similar, make sure
you use a submit button instead of a Javascript that submits the form.

Chirantan, look into the responds_to_parent plugin to do it via JS.
