All our k8s nodes are with same architecture and same Linux image. we are trying to bring up calico-node pods deamon set, the pod is failing to run on some nodes. and kubectl logs shows "standard_init_linux.go:219: exec user process caused: exec format error" for failing pods.

Where to get info about the failure? is it image issue or is it runtime issue?

Describe the results you received:
in some nodes pod went to craashLoopBackof

Describe the results you expected:
in all nodes pods must be running
