For a while host was not accesible from the network, and then it came back with log messages shown above. I've tried to tune samba socket options (SO_RCVBUF=16384 SO_SNDBUF=16384), and this fixed the problem for samba users. One interesting thing: copying file to windows XP machine worked fine, while Vista (SP1 x64) caused the problem. What solved the problem definitely was disabling TSO for re0 (ifconfig re0 -tso). I haven't notice any performance drop and it works fine, but I'm just curious what happened to the 'good' driver from 7.0-RELEASE. Best regards, -- _/_/ ..
