Hi everyone!

While trying to index some really big documents into an Elasticsearch  
cluster, we received the following error:

[2011-07-28 01:24:22,183][WARN][http.netty]

closing connection

How are you indexing data? It seems like an http header line was sent that  
is bigger than 4096?

Still strange that you get it, but, I added options to allow to control it:  
[Http Transport: Allow to configure `max_header_size`, `max_initial_line_length`, and `max_chunk_size` · Issue #1174 · elastic/elasticsearch · GitHub](https://github.com/elasticsearch/elasticsearch/issues/1174).

We're indexing using a custom written REST client. I'm actually not  
quite sure why the header sent was larger than 4096. I'll  
investigate.

Thanks though! 🙂
