[ovs-discuss] "ovs|00014|timeval|WARN|Unreasonably long 6567ms poll interval (232msuser, 5958ms system)" on OVS 2.6.0 & DPDK 16.07

[Bo Sun]

Hi Thadeu,

Finally, I switch to Open vSwitch 2.5.1 and DPDK 2.2.0 with identical
hugepage setup, and it works fine.

Using the stable version of OVS is a workaround to avoid this issue.

I searched for the error messages, and they are from a patch for Jumbo
Frames on Aug 9, 2016(
http://openvswitch.org/pipermail/dev/2016-August/077538.html).

It seems that I have to wait some time for this feature being more refined.

Thanks for your help.
