Connection Reset By Peer

Hi ALL,
Actually Client is sending data to the Tomcat apache server.
To send data
1.Create TCP Socket
2.In the TCP socket with sending request with HTTP/1.1
3. I am trying to send text/xml data nearly 15 KBytes.
4.Connections is rest by the server ( It send the RST-Reset) after 5 HTTP request
5..My requirement is to send atleast 64 Kbytes in a TCP socket

It is possible?
My doubt , why Server is sending Reset message??.
is it b'caz of
1.Time out ?
2.can we send only 5 HTTP request in a TCP socket

i don't think it because of the number of http requests? it doesnt make sense ? .
I think it may be the first reason , Time out
