Glad to hear you have found such a use for it.

Ok, that is interesting.

Ok, I have seen one or two such issues, but not for some time.
What version are you using?

Can you try the current git version, the last changes
that could affect this are:

    Use the BufferHandler and CachingBufferHandler from rnio instead of
    having our own copies.

    Try to make sure that growing buffers gets new content in the right
    place.

Especially the second entry sounds like it could affect your
problem.

Can you do:
git clone http://www.khelekore.org/rabbit/rabbit.git
cd rabbit
make 

If you do not have make you can build with ant instead.

Ok, do you have that capture in a format that can be shared?
Be careful, it may contain sensitive information, but still
if I can see the traffic it might be easier to diagnose this.

Could be, the code is supposed to try to read more in that case.

I do not think that your patch will work if you pipeline requests
though, so I do not think we can use it right away. Sadly the network
parsing is a bit complex to get right.
