Hello Trustin,

we noticed an issue When sending a large number of threads with small
messages, the netty Input server
for windows is resetting the TCP connection on a lot of the requests. 
Changing to a large file size does not show the issue.  So it seems the IS
is not handling the high rate of connection turnover with the small
messages.

Using tcpdump, we captured some tcp packages, and it seems the client does a
retransmission of the data, and the netty Input server comes back
immediately with a reset.  It appears to have not liked the retransmission.

I attached that tcpdump file.

Thanks
HP
