I'm guessing this is on WIndows? Windows has a weird (or wrong) treatment of SO_REUSEADDR. You can read more about it here: http://msdn.microsoft.com/en-us/library/ms740621(VS.85).aspx This has been discussed here before, but with no good resolution. One possibility is that we could make our use of SO_REUSEADDR configurable. /niklas
