I happen to be debugging a similar "I want to pull my hair out of my
head" problem right now (but with a different protocol....).

One thing that I've done to help me understand what is going on is to
rigorously go through each packet (sent and received) and verify that
what got sent is the same as what got received (on the customer's
network -- I can't reproduce this in-house...).  I build up a timeline
of major things that go on during the protocol interaction.

This was a hard work, but eventually I was able to come to some
conclusions about what might be going wrong.  I'm still testing my fix
though.  I feel like I'm living+breathing+sleeping this problem right
now.

Hope this helps.
