[KLUG Members] CLOSE_WAIT tcp connections

[greenproc]

>From my understanding of TCP/IP, CLOSE_WAIT means that the socket has
received a FIN from the other end of the TCP connection, and has sent an
ACK back in response (as it should), but the application holding the
local socket (your end) has not yet released the socket.

There is probably a better way, but you could always write a cron script
to kill any offending process id's found by netstat.  It really depends
on what application(s) aren't releasing the sockets, why, and how often.
