Thank you for the reply. Input interest is turned on.. and everything 
works fine normally. The backend is Tomcat.

However, at one of our client production sites, it seems like we 
encounter a socket reset only after we try to write it. I am just 
curious if anyone else has seen such an issue before. I have seen Tomcat 
resetting newly accepted connections after ACKing [at least some of] the 
packets when under load, but not seen resetting of a keepalive 
connection with a TCP dump which will help us verify our hypothesis.
