We can see the restart of iptables-alert pods automatically. Upon checking the last logs.

~~~
The Event "iptables-alert-5rz9s" is invalid: involvedObject.namespace: Invalid value: "": does not match event.namespace
~~~

    Unable to reproduce manually, however, it automatically reproduced in my test cluster

    There should not be any error.

    The reason I can see here is, there is a `null` value in pod_namespace in the iptables-alert script.

~~~
pod_namespace=$(crictl inspectp "${id}" | jq -r .status.metadata.namespace)
~~~

There comes a situation here, when it is unable to fetch the namespace of the pod from crio and we are receiving null.
