ovs-vswitchd CPU usage is high and lots of "ip netns" stuck in "D" state
Issue
-
Unable to reach dashboard / API for Openstack, all Instances are down. Incredibly small amounts of traffic get through now and again, but quickly go back down again.
-
ovs-vswitchd is running incredibly high CPU (600-1100%).
-
All three controllers have been standby and rebooted to begin to fix the issue but nothing improved the situation.
Environment
- Red Hat OpenStack Platform 10.0 (RHOSP)
