Dave enabled the receive buffer auto-tuning which uses TCP window scaling. It looks like all these sites are running FreeBSD, perhaps there is a bug in FreeBSD? As suggested earlier please get a TCP dump of a failed connection. To turn of receive buffer auto-tuning: sysctl -w net.ipv4.tcp_moderate_rcvbuf=0 sysctl -w net.ipv4.tcp_default_win_scale=0 Thanks. - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
