Seems you have an empty message there, since size is undef ? Check all the warnings you get, and correct the underlying problems before continuing. One step at time: check that you're message is ok, check that what you get is ok, insert print statements to assist you in debugging. Don't step forward to the next part of your program till you make sure that till that point everything is fine.
