--> After the Cluster upgrade to 4.16.38 some of the iptables-alerter pod are in Create Container Error State as shown:
pod/iptables-alerter-98mdm              0/1     CreateContainerError   0          23h
pod/iptables-alerter-bgzl7              1/1     Running                1          11d
pod/iptables-alerter-mpswn              0/1     CreateContainerError   0          5d

--> On seeing the pod yaml, the pods are only showing ContextDeadlineExceeded as shown:
containerStatuses:

        reason: CreateContainerError

--> Similar error can be seen in the events as well:

LAST SEEN   TYPE      REASON   OBJECT                       MESSAGE
5m          Warning   Failed   pod/iptables-alerter-98mdm   Error: context deadline exceeded
3m7s        Warning   Failed   pod/iptables-alerter-mpswn   Error: context deadline exceeded

--> Manually deleted the iptables-alerter pods, but no luck.
--> Manually restarted kubelet & crio service on the nodes, but no luck.
--> Pruned the nodes of the exited containers, no luck.
--> Hard & Soft reboots of the worker node from the VMware console, but no luck.
--> Also after wiping the CRIO for the node the issue persists.
