When we see the error messages pf rejects the packet because the acknowledgement number is too far out of the window it thinks the TCP sessi= on got to. However, it looks like it stopped updating the ack window some time ago, an= d I have no idea why it'd do that. The packets that should have updated it pass= ed through just fine. Is this 100% reproducible for this setup, or does it only happen occasional= ly? If so, how often? When did this problem start happening (I don't think we've touched any of the relevant code any time recently.)? --=20 You are receiving this mail because: You are the assignee for the bug.=
