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.

Hi All,
It worked fine for two weeks but I had a network outage 2 days ago then
today. Tried to disable rxcsum and txcsum after the first one, didn't
help. Don't know what else to do it's a shame that I can't use this card
with fbsd i REALLY don't want to install linux instead but my production
servers outages are not welcomed by the customers..
I tried to follow the thread but apologies if I've missed something. You
already tried disabling TSO but it didn't help, it seems. We need more
details here.
Can you get on serial console and check if you see anything when network
becomes unaccessible? Anything in dmesg or /var/log/message? Does
'netstat -m' show any buffer allocation failures when this happens?
You seem to indicate that this only happens at 'high' traffic. How much
is that traffic? Is this something that you can trigger easily?
Cheers,
Hiren
