How do you know it wasn't released?

Oh, an NT server maybe?  Rebooting Windows is the way, but not if you are 
talking about some flavour of UNIX.  This is a Linux admin list BTW.

Stop the server that is keeping the port open.  What port is it?  What is 
running on it?

First, check the status of the port with "netstat -at".

If there are any entries for the port in the LISTEN or ESTABLISHED
states, the port is still in use. You dan determine which processes
are associated with the socket using e.g. "fuser -vn tcp 80" (as
root).

OTOH, if there are connections in the TIME_WAIT state, you just have
to wait for them to time out.

port busy after server die.

Hello everyone, I have a nice question, I ran a WebServer, and after 8 
days hangs and die, but TCP port wasn't released.
I know that the solution is restart the system, but I see it in other 
times and this server can't be restarted.

There is some C function or command or anything that can release this 
port?


Thanks in advance.

Thanks, The webserver is a Java one from something called gadmin, 
application running on kaffe on uClib Linux environment, Of course I know 
the main solution is to find out  what makes the server die, with this 
commands, next time to this happens I will investigate, but I'm really 
shure, kaffe was not running, an after 2 days I decide to restart my 
Linux box, because I can't find out a solution, I'm a newbee about Linux 
Network Development.


Thanks. What is windows NT?
