  • if node conditions keep on changing , then timeout never checked

Case 2:

• machine obj = Pending , Node = Ready, node.gardener.cloud/critical-components-not-ready taint present on node, node conditions changed
  • Result : timeout not checked
  • if node conditions keep on changing , then timeout never checked

Post grooming issue

If node conditions keep flapping , then cloneDirty will become true in every reconcile, so timeout checking is always skipped.

should be dealt in controller runtime refactor.
