I ran into this issue about a year and a half ago. If this is the same = issue, it had something to do with the way an IPv4 address is bound to = IPv6. =20 I also ran into the issue on some older flavors of linux, though it = seems that the issue didn't happen on newer flavors. Sorry, I don't remember more details now. But, maybe someone else can = shed more light on the IPv4/IPv6 issue with UDP in Java.
