odd socket behavior

odd socket behavior

[Phy Prabab]

Hello all,

I am seeing something odd w/sockets.  I have an app
that opens and closes network sockets.  When the app
terminates it releases all fd (sockets) and exists,
yet running netstat after the app terminates still
shows the sockets as open!  Am I doing something wrong
or is this something that is normal?

TIA!
Phy

The socket is probably just lingering. Check the socket manual page in section 
7 (man 7 socket) for more information.

What do you see with lsof? Is there a process associated?

I'm seeing something related with 2.6.13...

Do you shutdown(2) them? Are these listening sockets?
