When killing side car of openshift-ptp pod, curling for clock class terminates with exit code 7 after side car is restarted 

- OCP 4.14.25
- ptp-operator.v4.14.0-202506112307

1.Run ptp and verify clock class with event enabled 

2.verify localhost9091:metrics  for clock class , should be 6  

$ oc exec -it ds/linuxptp-daemon  -n openshift-ptp -c linuxptp-daemon-container -- curl -s localhost:9091/metrics | grep clock_class

3.kill side car (daemon should be still running ) 
  
$ oc exec ds/linuxptp-daemon -c cloud-event-proxy -n openshift-ptp -- sh -c "kill -9 \$(ps aux | grep cloud-event-proxy | grep -v grep | awk '{print \$2}')"

 4. wait for the side car to recover 

 5. verify the clock class metrics again

    

$ oc exec -it ds/linuxptp-daemon  -n openshift-ptp -c linuxptp-daemon-container -- curl -s localhost:9091/metrics | grep clock_class
command terminated with exit code 7

 should report back metrics

In case linuxptp-daemon pod is deleted everything works again
