That is normal behavior for DPDK based applications.  It should not be considered a bug.

Subject: [Starlingx-discuss] DPDK 100% CPU

Abraham found a bug where DPDK is consuming 100% of the CPU time.

Has anyone else seen this?

There’s a bug filed on https://storyboard.openstack.org/#!/story/2002747, any comments, other sightings, debug advice etc.. would be most welcome!
