Well if it's not even hitting dataReceived then a more subtle exploration is 
not necessary! ;-)

So, wait a second.

You said you're looking at tcpdump, and it's showing you that your outstanding 
requests - in this case, 2188 and 2189 - are in fact being answered. But then 
you say you're looking at the dump from dataReceived, and seeing that not only 
are 2188 and 2189 not being answered from that layer, but 218a and 218b are 
being answered?

Simply put: that should be impossible.  TCP is an ordered stream.  If you 
received answers to 2188 and 2189 on the wire in tcpdump, you should see those 
come back to dataReceived first.  What kind of transport is this hooked up to?  
A regular socket?  Is there TLS involved?  Did you run tcpdump for that same 
session?
