Ok, have you thought about running a tcpdump and then examining the dump around the time that a drop occurs? (Specifically, if you know the connection that drops you can get wireshark to only display the packets for that dump). Also, have you compared netstat -s before and after drops? -- John Baldwin _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
