Could you manually double-check this? It sounds so weird that I'm afraid of an error in my script mis-interpreting your tcpdump's output format. In any case, I'm afraid you are not facing the kind of problems I inadvertently became a sort-of-expert in. Those 549-byte writes, should they prove real, may (others) give a hint what's going wrong, though.
