"Incomplete" requests are pretty normal - you can't expect that
single read() from socket will return you full request. To store
data that has been already read nginx uses either in-memory
buffers or disk buffers (for large request bodies).

The following configuration directives are available to fine-tune
buffers used:

http://wiki.nginx.org/NginxHttpCoreModule#client_header_buffer_size
http://wiki.nginx.org/NginxHttpCoreModule#large_client_header_buffers
http://wiki.nginx.org/NginxHttpCoreModule#client_body_buffer_size

See there for more info.
