I notice reproductible effect on my recent -current remote machine, after
5-7 hours of normal work, I can't connect to this machine via
ssh,telnet,pop3 or ftp, but smtp and http continue to work normally.

When I turn ipfw2 off, this effect is gone. It was never happened for old
ipfw with the same settings.

I have simple "open" firewall type with one "deny" rule for specific tcp
port. Since this is remote machine, I can't login and see what actually
happens during this effect. I also notice that if current connection stays
across beginning of effect, it continue to work, but new ones hangs.
