Content-Type: text/plain; charset=ISO-8859-15; format=flowed Content-Transfer-Encoding: 7bit Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org I don't know if I can quantify the issue very well, but since moving from 4.4-RELEASE to 4.5-RELEASE on my laptop, I've noticed that TCP-over-IPv6 sessions get stuck rather easily. They end up in a state where no further I/O will take place. TCP-over-IPv4 does not have this problem. This machine is using IPSEC over 802.11b (wi0 - a lucent gold card), and a (gif0) tunnel for IPv6-over-v4 (without any IPSEC since it's tunneling over v4 which is IPSECed anyway). Can anyone think of a reason why 4.5-RELEASE should be having problems in this area that 4.4-RELEASE did not?
