Define fragmented in a UDP context : how do you manage the packet ordering ?

It won't solve your issue. You most certainly handling the incoming
packets incorrectly somewhere in your IoHandler. Typically, you are not
in the same session when 2 UDP packets are coming, thus the IoBuffer,
which is stored into the session, is different for each incoming packet.
