There were recently some delayed ACK fixes in FreeBSD, which earlier cause problems in rare situations (when FreeBSD is receiving large windows of data.) It is rare, but you can try turning delayed ACKs off with: sysctl -w net.inet.tcp.delayed_ack=0 but if it doesn't help, I would leave it on. Anyway, my first guess would be hardware problems somewhere along the line. -Paul. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
