Look at the interrupts per queue. 500,000 is the maximum and it is the
reason your interface is not accepting new packets.

I’ve noticed that there have been reports of problems with Intel
X520-SR2 network interfaces stopping working. I think I’m seeing a
similar issue where the 10Gb interfaces stop receiving traffic
(they’re being used in promiscuous mode to sniff traffic from a tap).
ifconfig shows the interfaces are still active and the links are OK.
ifconfig down/up restores activity. I’ve changed
hw.intr_storm_threshold=8000 but I couldn’t tell if the interrupt
storm threshold had been triggered at the time the interfaces stopped
passing traffic.
Output from sysctl:

Hi,
I had this problem and one day updated the system 10.1- RELEASE to 10.1- STABLE
and the problem stopped. I was one years with this problem and a script running
and testing the interface when the interface stopped working I was doing
exactly what you did. Today I no longer have that problem anymore.
I'm using 10.1-STABLE r281235
Thanks for the indication of success with 10.1-STABLE. I am locked into using
FreeBSD 9.x until I can go through the whole integration and acceptance testing
cycle for 10.x, so I’m trying to find a solution that works on in 9.x. I have
reviewed the diffs between 9.3 and 10.1-STABLE for ixgbe driver and haven’t
noticed anything that stands out.
Guy,
I may be wrong but I think the change was not the ixgbe driver.
