Hi Guys,
after long googling and trying to find the right setup for nginx and
fastcgi
we came to three settings:
fastcgi_buffers, fastcgi_buffer_size and fastcgi_read_timeout;

According to HttpFcgiModule manual the buffer size is equal to the
size
of one buffer in fastcgi_buffers by default. Are this settings correct
because a few hours later we are still getting BadGateway error ?

We are using Feebsd 8.2-STABLE amd64 jails and nginx from ports
sysctl hw.pagesize
hw.pagesize: 4096

fastcgi_connect_timeout 60;
fastcgi_send_timeout 20;
fastcgi_read_timeout 60;
fastcgi_buffers 512 4k;
fastcgi_buffer_size 4k;
fastcgi_busy_buffers_size 256k;
fastcgi_temp_file_write_size 256k;
fastcgi_intercept_errors on;
fastcgi_ignore_client_abort off;
