As I'd recently posted on -current, I've been noticing TCP oddities in 3.3 and 3.4. I've got a pn card (NetGear FA310tx) and a few new things to report: - Invariably, a TCP connection will freeze with something in the send queue. Connections don't freeze even if there's something in the receive queue. - tcpdump-ing the pn0 interface shows that the host thinks that it's sending data. tcpdump-ing elsewhere in the network shows that pn0 isn't actually transmitting anything into the wire. - This really is a TCP or interface bug because NFS connections don't freeze using UDP. - Other TCP connections continue to operate (like a cvsup in the background) I haven't stared at the if_pn.c code all that closely but I'm willing to entertain debugging suggestions. -scooter To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
