FIN_WAIT_2 on FreeBSD 6.2-STABLE

[Stefan Lambrev]

Hi,

I'm seeing strange problem with sockets in state FIN_WAIT_2.

netstat -n |grep FIN_WAIT_2|wc -l
shows 12234 lines, Those sockets never die and just grow more and more, 
when finally today I saw this in logs:
postfix/smtp[6968]: connect to gmail-smtp-in.l.google.com[66.249.91.27]: 
Can't assign requested address (port 25)
and this happens not only to postfix, but all clients & servers on this 
host.
Even things that use only local connections throw out: connect: Can't 
assign requested address

Shorty after I moved away almost everything from this server, there was 
a spontaneous reboot.

I know what apache and some buggy clients can cause sockets to stay in 
state FIN_WAIT_2, but they should disappear
after some timeout.
Is there a point to go for 6.3-prerelease, or nothing like this was 
reported, respectively fixed between may 2007 and today?
Migration to RELENG_7 is not option for me at this point as this host 
serves something like 6mbps of http traffic,
and there is a report that sometimes hosts running releng_7 can't be 
reached ..

6.2-STABLE from May 9 - amd64

Thanks in advance.
