Hello,
My setup is the following:
CPU: Intel(R) Xeon(R) CPU X5687 @ 3.60GHzNIC: Intel 82599EB
OS: Ubuntu 10.04 64-bit with kernel: 2.6.32-40driver: ixgbe 3.22.3 , which I
compiled and installed from source.
There are two physical interfaces on the NIC: eth0 receives 3 Gbps and eth1
receives 5 Gbps of traffic (maximum traffic). No traffic is transmitted.The
ixgbe driver is loaded with all the default parameters.
I see packet drops, the number rx_missed_errors in "ethtool -S eth1" is
increasing. This happens only on the eth1 interface from time to time, when the
total traffic exceeds 7 Gbps. At that time, the CPU usage of ksoftirqd process
increases at 100%.
Also, ethtool -a eth1:#:/usr/src# ethtool -a eth1Pause parameters for
eth1:Autonegotiate: offRX: onTX: on
and ethtool -S eth1 is attached.
Any idea on what the problem is?
BR,Stathis
