The question is : how many connections to your server is the HAPPI
client opening ? If it opens one single connection that is shared across
many users, then you are screwed : all the messages will be handled by
one unique session, and at some point, due to TCP fragmentation, it's
likely that some messages will get garbled or intermixed.
You have to provide some more infos about how is your client working.
