Hi All,
I've got almost the same problem with intel 82574L based nic. My platform is
nvidia ion running Atom 1.6 and nic is an external PCI-express adapter.
Unlike Jason's case mine is always stuck in receiving traffic, it's Ierrs
increasing while Ipkts not. Thanks to Jason's script I can see those locks
and interface flapping every several hours. My system is not a heavy loaded
server but just a home nas/router, usually routing at 100 mbps or less.
Nither disabling MSIX nor tuning txd rxd doesn't help me.
Hi,
When this occurs, does this completely lock up with RX traffic? Ie,
_no_ valid RX traffic occurs?
If so, does the error count increase 1:1 with what traffic you're
trying to send to it?
Hi Adrian
Yes, it's completely locked - ping packet loss to the interface is 100%,
I also managed to run tcpdump -ni em0 and there were only outgoing
packets from the interface but no packets arrived to the interface. As
for the error counter ratio - I'm not sure about it, don't know how
check this besides comparing counters on the switch with interface, but
it's a little bit complicated to catch in time.
