Ah..., the joys of a hyperthreaded machine, I bet. I'll see what I > can dig up. Thanks for the reply. I'm about to give up and go home for the weekend. Here is where rlogin is stuck in the child process: #16 0x61049408 in fhandler_socket::wait (this=0x616e50a4, event=0x6e8) at ../../../../cygwin/winsup/cygwin/fhandler_socket.cc:723 #17 0x61049b92 in fhandler_socket::recvmsg (this=0x616e50a4, msg=0x22eb10, flags=0, tot=8192) at ../../../../cygwin/winsup/cygwin/fhandler.h:365 #18 0x6104963f in fhandler_socket::readv (this=0x616e50a4, iov=0x22ebc0, ---Type to continue, or q to quit--- iovcnt=1, tot=8192) at ../../../../cygwin/winsup/cygwin/fhandler_socket.cc:800 #19 0x6109fc2e in readv (fd=3, iov=0x22ebc0, iovcnt=1) at ../../../../cygwin/winsup/cygwin/cygheap.h:303 #20 0x6109f95c in read (fd=3, ptr=0x404070, len=8192) at ../../../../cygwin/winsup/cygwin/syscalls.cc:369 just one stupid question... I'm probably way off base, but it looks like the WSAEnumNetworkEvents call on line 726 of fhandler_socket.cc might return events for the parent process's copy of the socket as well as the child's in a forked process. Could that be an issue? I'm just grasping at straws that I don't understand and trying to be helpful at the same time :-). -- Brian Ford Senior Realtime Software Engineer VITAL - Visual Simulation Systems FlightSafety International the best safety device in any aircraft is a well-trained pilot... -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
