This is long standing issue in DPDK e1000 driver likely caused by bad e1000 emulation. Still, bad emulation is still not good excuse for lack of error message throttling.
There is even patch submitted to fix this issue: http://dpdk.org/dev/patchwork/patch/11622/ <http://dpdk.org/dev/patchwork/patch/11622/> But it never went upstream… As Dave suggested, switch to vmxnet3 will solve this issue… Thanks, Damjan > On 25 Jan 2017, at 14:54, Andrew Li (zhaoxili) <zhaox...@cisco.com> wrote: > > Thank you, Dave, and Damjan, that’s clear enough for this question…We’ll plan > to switch to Vmxnet3 then. > > - Andrew > From: "Dave Barach (dbarach)" <dbar...@cisco.com <mailto:dbar...@cisco.com>> > Date: Wednesday, 25 January 2017 at 9:37 PM > To: "Andrew Li (zhaoxili)" <zhaox...@cisco.com <mailto:zhaox...@cisco.com>>, > Damjan Marion <dmarion.li...@gmail.com <mailto:dmarion.li...@gmail.com>> > Cc: "vpp-dev@lists.fd.io <mailto:vpp-dev@lists.fd.io>" <vpp-dev@lists.fd.io > <mailto:vpp-dev@lists.fd.io>> > Subject: RE: [vpp-dev] Error reading from file descriptor 9: Input/output > error > > Vmxnet3 interfaces are strongly preferred: for performance, as well as to > make this specific issue disappear. <> > > We have a patch floating around which turns off the disk-filling syslog > message, but if you simply switch to vmxnet3 interfaces the pain will go away > without rebuilding images, etc. etc. > > HTH...
