      Description of problem:

      A customer reported one of the 120 nodes to not being able to start pod for the error:

"failed to configure pod interface: timed out waiting for OVS port binding (ovn-installed)"

The ovn-controller is reporting:

"poll_loop|INFO|wakeup due to [POLLIN][POLLHUP] ... (98% CPU usage)"

But the process consuming more CPU on the node is ovn-controller itself.

      Version-Release number of selected component (if applicable):

      4.12.15

      How reproducible:

      not known

      Steps to Reproduce:

      1. install cluster with OVN 
2. configure several networkpolicies and services
3.

      Actual results:

      ovn-controller is consuming too much CPU impacting OVS

      Expected results:

      ovn-controller CPU usage should not harm the node
