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;

events {  
worker\_connections 1024;  
}

http {  
include mime.types;  
default\_type application/octet-stream;

```
# no sendfile on OSX uncomment
#this if your on linux or bsd
#sendfile on;
tcp_nopush on;
