Re: FreeBSD 9.3 - Intel X520-SR2 stops passing packets

If you are having high interrupt rate, it will be same on latest 10-STABLE. Are you using an unsupported SFP? > Guy Helmer > May 28, 2015 at 6:24 PM >> On May 23, 2015, at 1:14 PM, Babak Farrokhi wrote: >> >> Look at the interrupts per queue. 500,000 is the maximum a

Look at the interrupts per queue. 500,000 is the maximum and it is the reason your interface is not accepting new packets. > Guy Helmer > May 21, 2015 at 6:03 PM > I’ve noticed that there have been reports of problems with Intel > X520-SR2 network interfaces stopping

Re: FreeBSD 9.3 - Intel X520-SR2 stops passing packets

Are there any log messages printed out by the driver? The sysctls don't really look out of the ordinary, other than the number of sub-64 byte packets. On Thu, May 21, 2015 at 9:10 AM Guy Helmer wrote: > > > On May 21, 2015, at 8:52 AM, Christopher Forgeron > wrote: > > > > A few things: > > > >

Re: FreeBSD 9.3 - Intel X520-SR2 stops passing packets

A few things: 1) How long before you have this behaviour? 2) What's the output of 'netstat -m' when you have the problem? 3) What is your MTU set to, and do you have TSO on or off? On Thu, May 21, 2015 at 10:33 AM, Guy Helmer wrote: > I’ve noticed that there have been reports of problems with
