I was not thinking clearly. As you found, that's never going to work even if try to use unsupported command line operands. Netstat is not reporting the original socket number. I have no idea if this is by design or a netstat defect. I wonder if a brute force approach might work - close the sockets that ar= e not listed as open as in run netstat -s to collect a list of open sockets for socket =3D 1 to 32767 if socket not in list soclose socket end The stack knows the FIN_WAIT_2 socket number or it would not be able to prevent it from being reused. The question is is there anything that can= be done to speed up to full release the socket resources.
