Cookie too large, nginx returns a 400 and doesn't log it.  Unfortunately there isn't much we can do about the cookie size.  With the fb connect iframe stuff there are other parties setting cookies on our domain.

Which buffers did you set?

You probably need to adjust client_header_buffer_size and 
large_client_header_buffers.

See http://wiki.nginx.org/NginxHttpCoreModule#client_header_buffer_size 
and http://wiki.nginx.org/NginxHttpCoreModule#large_client_header_buffers./
