Wasn't there a thread like this just recently that Corinna was helping someone with a problem and it was to do with some kind of "winsock handles aren't quite like other handles when it comes to duplicating them" problem? I'll have a search through my old emails and see if I can find it. Hikaru, are you fully up-to-date with the latest Cygwin DLL? And is it possible for you to strip down your code to a tiny testcase using just the minimal code to open the socket, accept the connection, fork the child and call _exit, so that hopefully we can reproduce the problem? cheers, DaveK -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
