sockets without owner.

Hello list,

I'm having very strange problem.
I have near 200 sockets reported by netstat -An, which are NOT reported 
by sockstat and fstat.
All of them look like (output from netstat -An) :

ffffff0169282000 tcp4       0      0  192.168.13.12.4965 
192.168.13.3.8080  FIN_WAIT_2

I'm trying to figure out what keeps them active (tcpdump shows traffic 
from 192.168.13.12 to 192.168.13.3)
The application that create them is stopped before more then a week but 
request are still "flying" around.

I tried fstat |grep ffffff0169282000, but the output is 0 lines.
Is there any way to close those sockets, as it appears that they are 
stalled and without owner?

And what is the timeout for FIN_WAIT_2 in freebsd ?
(the rfc doesn't define timeout but I read somewhere that freebsd's 
network stack have timeout)

FreeBSD 6.2-PRERELEASE SMP amd64.

I have access to both IPs - 192.168.13.12 is http balancer and 
192.168.13.3 is apache server (both were restarted)
