I have a port that is blocked by a process I needed to kill. (a little telnet daemon that crashed) The process was killed successfully but the port is still in a 'FIN_WAIT1' state. It doesn't come out of it, the timeout for that seems to be set to 'a decade'. The only way I've found to free the port is to reboot the entire machine, which is ofcourse something I do not want to do.

$ netstat -tulnap | grep FIN_WAIT1 
tcp        0  13937 10.0.0.153:4000         10.0.2.46:2572          FIN_WAIT1  -

Does anyone know how I can get this port unblocked without rebooting?
