TCPIP FIN_WAIT_2 state   
Hello,

QNX632, x86

I need information about a TCP-IP issue.
We are Server in a tcp-ip connection and after a disconnection request, the line stay in FIN_WAIT_2 state and never go 
out this state. Nomore connection could be done. The only way to restore the connection is reboot our PC. Is it possible
 to bypass this state or set a timeout to go out this state and terminate the connection?

Thanks for Your help.

RE: TCPIP FIN_WAIT_2 state   
From the Net

"The FIN_WAIT_2 state comes immediately after receiving an ack from the
server of the client's original FIN (generated in the FIN_WAIT_1 state).
The reason that you are seeing connections 'hanging' in the FIN_WAIT_2
state is because the application has not received a final FIN from the
server".

Sounds like the client isn't sending out the final message for some
reason.


	Robert.

But it should time out eventually.  Around 9 minutes
IIRC.

RE: TCPIP FIN_WAIT_2 state   
Oops... Forgot to add:

Does setting the SO_REUSEADDR socket option on your connection help out?
