Hello, yesterday one of our clients did something interesting (stupid): they connected both ends of an UTP cable to the same switch, to which our FreeBSD server was also connected. The server was immediately completely unresponsive from yesterday evening until this morning, when our tech guy went there to see what the problem was. Even when they rebooted the FreeBSD machine, it wouldn't boot normally - disk I/O was very busy and everything was happening unusably slow. After the disconnect from that switch, everything went back to normal.
Any ideas how to prevent such situations in the future? (I would like to do it on the server side, not on the "user side".) Thanks, Nejc
