Strange Problem with 16 byte packets

Thanks i will. However, the doubt is that what does introducing a 16 byte
data into the steam does that causes the session to time out. I added
instrumentation to push some dummy data so that instead of 16 bytes, we
push 1 MB of data. In that case i saw no issues. Any idea if there is a
firewall setting that could be coming into play here?
