which is mine crash log: It looks like it crashed inside gethostbyName, Do I need to add some special protection when I call gethostbyName?

Before we get into the crash here, what are you looking to do with gethostbyname and why is it being used with CFNetwork APIs (as the tag infers)? More specifically, why are you trying to do that you cannot just connect-by-name instead?
