The interesting detail is it would always stop at exactly 64 sockets open; which is the maximum number for which select() doesn't have to spawn a second thread.

The fools aren't getting in anyway. I turned off password auth. -- 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
