Er, a few points...
First, TCP_NODELAY should only be set (using setsockopt, see "man setsockopt",
"man tcp", and "perldoc -f setsockopt") when you have very fine timing
demands. TCP_NODELAY settings should never cause a message to be lost
(but it might receive a fraction of a second later than with
TCP_NODELAY set). So, TCP_NODELAY is likely not the problem here.
Second, including a short fragment of code that illustrates the problem
would be helpful.
Third, why are you Cc:ing this to me? Are you under the (wrongful) impression
that I'm an authority on TCP_NODELAY?
