Sockets have to be explicitly closed. They are generally closed automatically by exit(), which will close all the fd's a process has open. I agree with the previous poster, that it looks like a bug you will need to fix or workaround. It looks like what's happened is that you have a deadly embrace deadlock, where you've sent data both ways and then exited. One thing to try might be to either turn off keepalive via sysctl, or explicitly disable keepalive on the sockets, first thing after opening them. -- Terry
