      https://bugzilla.redhat.com/show_bug.cgi?id=1944121 is back, see errors in on one of the two nodes on which the pods are running.
      
      
      
      

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

       

      How reproducible:

      Most of the time - automated test failed and also see it for manual 

      Steps to Reproduce:

      1. Create a project test
      2. Create two pods in the project
      
       oc create -f https://raw.githubusercontent.com/openshift/verification-tests/master/testdata/networking/list_for_pods.json 
      replicationcontroller/test-rc created
      oc get pods -owide
      NAME            READY   STATUS    RESTARTS   AGE    IP             NODE                                         NOMINATED NODE   READINESS GATES
      test-rc-brhgw   1/1     Running   0          3m2s   10.131.0.173   ip-10-0-174-101.us-east-2.compute.internal   <none>           <none>
      test-rc-zlfjr   1/1     Running   0          3m2s   10.129.2.115   ip-10-0-146-11.us-east-2.compute.internal    <none>     
            <none>
      
      3. Create two policies
      cat policy.yaml 
      ---
      # Source: networkpolicies-config-values/charts/networkpolicies-config/templates/networkpolicies.yaml
      kind: NetworkPolicy
      apiVersion: networking.k8s.io/v1
      metadata:
        name: stex-rd-networkpolicies-config-default-deny
      spec:
        podSelector: {}
        policyTypes:
          - Ingress

      # Source: networkpolicies-config-values/charts/networkpolicies-config/templates/networkpolicies.yaml
      kind: NetworkPolicy
      apiVersion: networking.k8s.io/v1
      metadata:
        name: stex-rd-networkpolicies-config-allow-dns
      spec:
        podSelector: {}
        egress:
        - to:
          - namespaceSelector: {}
          ports:
          - protocol: TCP
            port: 53
          - protocol: UDP
            port: 53
          - protocol: TCP
            port: 5353
          - protocol: UDP
            port: 5353
        policyTypes:
          - Egress
      
       4.Delete the project
      oc delete project test
      project.project.openshift.io "test" deleted
        5. Check the logs of ovn-controller container
      oc -n openshift-ovn-kubernetes get pods -owide
