Network going down

M

marvel

Hi all,

I have a new server running FreeBSD with an Intel 10 Gbe NIC running FreeBSD 9.2.

Now, when I'm downloading multiple torrents and the speed increases to 70 - 80 MB/s the network suddenly goes down with no error message at all. I then need to restart the network and it works again for a couple of minutes. If I limit my downloads to 1 or 2 torrents everything is fine, so I have the feeling I'm hitting a limit somewhere, I wouldn't expect the network to go down though.

Any idea what this could cause? I've been googling a lot but couldn't find similar issues.

Thanks!
 
You may want to fix the speed/duplex settings on both the card and the switch. It's possible the network drops because the auto-negotiation fails for some reason.

Is this a card that uses the ixgbe(4) driver? I see occasional unexplained slowdowns, which can usually (but not always) be fixed by doing kldunload ixgbe; kldload ixgbe. Which only works if you're using the driver as a module, not compiled into the kernel.

Do you see any unusual kernel messages in dmesg(8)?
