Yeah, I considered using a packet sniffer, but haven't due to the timing 
issue.

Unfortunately, the machines in question are located on-site in a 
customer's data center. The only machine I have access to is the Linux 
machine that's the client side of the conversation. I'm going to have to 
step things back, verify that I can reproduce the issue with no 
debugging again and then see if I can figure out a way to get more data 
out of the connection.
