i have two sr proxies talking with each other over

other tcp packets get through from 3.0 sr host to 3.1 sr host. netstat
on 3.0 sr host shows that tcp connection to 3.1 sr host is in
ESTABLISHED state whereas netstat on 3.1 sr shows that the same tcp
connection is in FIN_WAIT1 state. it takes several minutes before the
hanging tcp connection is replaced by a new working one. there is no ip
level connectivity problem between the two sr hosts.
any suggestions on what might be going on? is there some known bug in
3.0 tcp implementation that could explain this?
There is no known bug in 3.0 and even if it would be, the connection
should go automatically in close-wait on 3.0 (without the userspace
doing anything).
It looks like somehow the 3.0 does not receive the FIN (local firewall
rules?).
