that's correct, disabling TSO didn't help however I did not disable vlanhwtso so it's my next step but I don't use vlans. I can access the server via IPMI checked the netstat no buffer problem there, no error in /var/log/messages just the ntpd no route to host caused by the network outage. about high traffic: during the night other server sent 10GB backup to this server via em0 interface. the problem is much more the transfer rate than the size of the file, but I can't reproduce it just wait to happen again.
