In 1.1.73 I can see that some sockets are staying around forever in
FIN_WAIT2 or LAST_ACK or ?? state. The timers appear to change but the
retries don't change and the sockets don't disappear. Did /proc/net/
change again (ie do I need a new netstat?) or is this a bug?
here's the output of
netstat -ton; sleep 1; netstat -ton

somethings odd with this. maybe I should do a make clean and rebuild to be sure.
here's cat /proc/net/tcp:
