Perhaps a general question but, you suspect one of the pods is having issues, you don't know what exactly. What do you do?

Start by inspecting the pods status. we can use the command kubectl get pods (--all-namespaces for pods in system namespace)

If we see "Error" status, we can keep debugging by running the command kubectl describe pod [name]. In case we still don't see anything useful we can try stern for log tailing.

In case we find out there was a temporary issue with the pod or the system, we can try restarting the pod with the following kubectl scale deployment [name] --replicas=0

Setting the replicas to 0 will shut down the process. Now start it with kubectl scale deployment [name] --replicas=1
